zsh-4.0.7 memory fault in IRIX 6.5

zsh-4.0.7 memory fault in IRIX 6.5

[Joachim Backes]

Hi,

having problems with zsh-4.0.7 (and earlier) on IRIX-6.5:

if I have an (very old) /etc/zshenv with the contents

        setopt shwordsplit

then zsh dies directly after start with "memory fault". The reason
seems to be the (invalid ??) contents of /etc/zshenv.

I made a system trace of zsh and got the following (the first lines
are omitted) result:

...


   18mS[  3]                 : ioctl(10, TIOCGSID, 0x7ffb7de0) OK

   19mS[  3]                 : fcntl(3, F_DUPFD, 10) = 11
   19mS[  3]                 : close(3) OK
   19mS[  3]                 : fstat(11, 0x7ffb7d10) OK
   19mS[  3]                 : sigaction(SIGINT, {flags=0 handler=0x1006b0d0 mask=[<none>]}, 0) OK
   19mS[  3]                 : fstat(11, 0x7ffb6b10) OK
   19mS[  3]                 : ioctl(11, __OLD_TCGETA, 0x7ffb6ac0) errno = 25 (Inappropriate I/O control opera
tion)
   19mS[  3]                 : read(11, "setopt shwordsplit\n", 4096) = 19
   20mS[  3]                 : sigprocmask(SIG_BLOCK, [SIGCLD], [<none>]) OK
   20mS[  3]                 : received signal SIGSEGV

An empty /etc/zshenv makes no trouble.

I can't imagine anything that would confuse zsh users more (I can think
of a few that would confuse them just as badly) but I suppose if you are
the only one on the system ...

} then zsh dies directly after start with "memory fault". The reason
} seems to be the (invalid ??) contents of /etc/zshenv.

Does it matter _what_ the contents are?  That is, if you change it to
something other than 'setopt shwordsplit' does it still crash?

Just because I have it in the SGI section of my own .zshenv, try this
as the very first thing in /etc/zshenv:

if [[ -n "$ENVONLY" ]]
then
    unsetopt zle
fi
