Neither could I, hm.

Yup, forgot to test the other path-prefix parameter.

~/src/she* has 1 match - a directory ``~/src/shells''.  Also, ~/src is
the only thing starting with s in ~ if that's relevant.

I just got a dump at the same line - during startup - when it's going 
through the init files /etc/z* + ~/.z* - but it's not occuring every time
which makes it somewhat more troublesome.  It may be a memory allocation
problem from elsewhere manifesting there, but I don't know anything about
that code so ....

You haven't said how many possible completions of ~/src/she* there are,
or whether there are any symlinks involved, so I can't be sure I'm
trying the right things ...

However, I can get this minor odd behavior:

    zsh% ~/zc<TAB>
    zsh% ~//zc

There is no possible match for "zc", though there are three directories
with names starting with "z".  The slash gets doubled only when there's
no possible match.

BUG: 3.1.5-pws-11 completion coredumps

[Geoff Wing]

Heyla,
may be fixed in pws-12 but nothing in pws's list seemed to indicate so.

Couple of core dumps with completion. pws-11 with all completion stuff
installed.
Doing ``~/src/she<TAB>'' (AUTO_CD obviously) at the prompt gave me:

~/src/she       BUG: attempt to free storage at invalid address
BUG: size wrong in freenode()
BUG: attempt to free storage at invalid address

and I think I just overwrote it with another coredump (doing the same
sort of thing) so this trace might not match the above note - but I've
kept this dump in case further information is required.

This is totally unmeaningful to me but someone who knows the structures
might be able to ask for the appropriate information.
