With zsh 5.2 under Debian/unstable, zsh sometimes crashes when
I do:

I'm attaching the full backtrace.
This seems quite random: I can sometimes reproduce the crash,
but not always.
Ditto from the mpfr working copy (instead of mutt), so that this is
not specific to some software.

Looks like something's already gone wrong by this point, since

this has remembered the value of an apparently invalid previous value of
patinput up above... although that's not guaranteed, since it may
simply be pointing to tne end of memory, which is valid as long as it's
not dereferenced (I had this while debugging a few months ago).
Does valgrind give any information?

What's the minimal zshrc required to reproduce the crash? Does it
happen with 'zsh -f' + 'autoload compinit && compinit'?

Yes, this is the kind of crash where the stack trace is probably not
very helpful, because frames have returned and/or new frames entered
an unknown number of times after the pointers went awry but before
the bad dereference that trips the fault.
Shot in the [mostly] dark: I see TRAPCHLD embedded in one of the strings
in your backtrace. Completion after "configure --" forks at least one
child process (says valgrind) so if you have a TRAPCHLD function it's
possible that it's corrupting something. We do attempt signal handling
during pattern matching in order that deep recursive globs can be stopped
with SIGINT; it could be that needs a bit more regulation.

It may be difficult to find out since it can take some time to
reproduce the bug.

I haven't managed to reproduce it with that.

FYI, here's my TRAPCHLD:
TRAPCHLD()
{
if [[ -o interactive && -n $TTY ]] then
updprompt
typeset -g _trapchld_called=1
fi
}
with:
updprompt()
{
psvar[2]=""
unset _trapchld_called
local njobs jobstr
njobs=$#jobstates
[[ $njobs -gt 1 ]] && jobstr="s"
[[ $njobs -ge 1 ]] && jobstr=" $njobs job$jobstr |"
[[ -n $TTY && $TERM == (xterm*|dtterm|mlterm|rxvt*|screen*) ]] &&
{
[[ $TERM == screen* ]] || print -nP "\e]1;%m${ptsn:+[$ptsn]}:%.\x07"
print -nP "\e]2;${jobstr}${WINTITLE:+ $WINTITLE |} %n@%m - %~ | %y\x07"
} > /dev/tty
[[ -n $_trapchld_called ]] && updprompt
}
I can't reproduce the bug if I remove:
[[ -n $TTY && $TERM == (xterm*|dtterm|mlterm|rxvt*|screen*) ]] &&
{
[[ $TERM == screen* ]] || print -nP "\e]1;%m${ptsn:+[$ptsn]}:%.\x07"
print -nP "\e]2;${jobstr}${WINTITLE:+ $WINTITLE |} %n@%m - %~ | %y\x07"

} zsh doesn't work with valgrind:
I have not had any such issues. However, I *don't* configure with the
--enable-zsh-valgrind option, so it's possible that the extra code that
this option adds to mem.c has broken something.

What if you just remove the $TERM comparisons, i.e. leave the test of
$TTY and the print statement?
There are two static globals in pattern.c:
/* Flags used in both compilation and execution */
static int patflags; /* flags passed down to patcompile */
static int patglobflags; /* globbing flags & approx */
I'm guessing that re-entering pattern matching during the signal handler
is messing up those globals and leading eventually to the crash.

Try the patch below? Unfortunately this is likely to slow Jesper's
massive glob a little more. The right thing would be to factor out
the globals, but there are about 100 references to them so that's
going to be a large code change.

I can't reproduce the crash if I remove these comparisons.
I'll try the patch tomorrow.

Well, foo.
Can you repeat it if you configure with --disable-multibyte ? Sorry for
so many trials, just trying to narrow it down to things that might be
messed up by re-entering matching (as opposed to pattern compilation).

Same problem with zsh 5.2 configured with --disable-multibyte,
whether I use the patch or not.

That's opt=${opt##[[:space:]]##} so it seems to indicate that we've gone
into an infinite loop, but the underlying cause (global pattern matching
state being messed up by re-entering through a signal handler) is still
the most likely culprit.

Yeah, nothing really new here, this is exactly what I would expect
to see: The hander returns and thereafter pattern matching is messed
up and crashes when it tries to pick up where it left off.

We could add a variable that triggers an abort when the signal handler
runs in pattern matching, but does that tell us anything beyond, er, it
was running in pattern matching? If not, what sort of information could
we get from this? Dump some state when we return from the signal
handler and detect we've been in it? Or is that if we know we've been
int he signal handler at that point we already know the place where we
needed to queue signals...
I don't think I've actually suggested anything.

I don't remember exactly, but several dozens.

Could there be some logging to know what happens internally?

We could convert the pattern matching globals to macros that execute
code whenever the globals are accessed:
diff --git a/Src/pattern.c b/Src/pattern.c
index 72c7d97..a4fb24f 100644

Now, f() can assert() some invariant, or check if SIGWINCH had been
delivered (and if so, drop into a gdb breakpoint), etc...
I'm proposing this just as a means of debugging for this one problem,
not as a permanent change.
Cheers,

There are a number of globals, and the symptoms are such that I don't
think the problem is limited to the ones that are commented as being
used by both compilation and matching. It acts as though one of the
data structures or pointers has been moved and not restored.

Well, I think I've isolated this, but I don't know what to do about it.
The set of globals that are getting messed up are these:
/*
* Run a pattern.
*/
static char *patinstart; /* Start of input string */
static char *patinend; /* End of input string */
static char *patinput; /* String input pointer */
static char *patinpath; /* Full path for use with ~ exclusions */
static int patinlen; /* Length of last successful match.
* Includes count of Meta characters.
*/
static char *patbeginp[NSUBEXP]; /* Pointer to backref beginnings */
static char *patendp[NSUBEXP]; /* Pointer to backref ends */
static int parsfound; /* parentheses (with backrefs) found */
This set is all referenced from pattryrefs() and other functions that it
calls. The problem is that they also describe the state of backrefs, so
it's difficult to save/restore them such that $match et al. remain sane
across a signal handler (and when not sane, they point off into unknown
territory and crashing ensues).
The problem is that it's exactly during the time that these globals are
volatile that we want to allow signal handling, so that a deep recursive
glob or pathological pattern match can be interrupted [see patmatch(),
"while (scan && !errflag)"].
The patch below crams all those globals into a struct so they can be
saved/restored as one, and then tries pushing the signal queue management
down into patmatch() from pattryrefs(). A side-effect of this patch is
that the following is no longer guaranteed to work:
typeset -i trap_handled;
TRAPUSR2() {
setopt localoptions extendedglob
[[ $somestring = (#b)$~somepattern ]]
trap_handled=1
}
TRAPUSR1() {
[[ $TERM = screen ]] && print $something
}
while true; do
if ((trap_handled)); then
trap_handled=0
print $match[0] # This may not be the backref from TRAPUSR2
fi
done
Specifically, if the signals arrive in order USR1 USR2 such that USR2
is handled during the [[ ]] expression in TRAPUSR1, then the state from
TRAPUSR2 will be discarded. I don't know if/how we ought to document.
Of course if this DOESN'T solve Vincent's crash, then all of the above
is moot because I've mis-diagnosed again.

Are you simply worried that a pattern match that happens asynchronously
might not leave behind $MATCH / $match etc. values after return owing to
other asynchronous goings on with pattern matching? I don't think
that's an issue. I'm sure there must be other examples of this.

The point is that a pattern match that happens asynchronously might not
leave behind $MATCH / $match etc. values owing to other pattern matches
going on, period, whether synchronous or async. Two signal handlers in
the example was just to set up a way to get into the situation; a glob
that takes several seconds to complete might just as easily do it, but
is hard to invent for purposes of example code.
I'm the tiniest bit worried that there's a way $MATCH et al. might be
left pointing at garbage memory, but I don't really think so.
} I don't think that's an issue.
I don't think it's an issue either, but it's going to do the potentially
unexpected thing more consistently now, so I wondered if it should be
documented.

Sorry for the late reply, I was very busy. It seems that it solves
the crash! What I did is:
1. Compile and install zsh 5.2.
2. Check that the crash is still reproducible, and it is.
3. Apply this patch.
4. Recompile and reinstall zsh.
5. Test whether the crash is reproducible, and I couldn't reproduce it.
