>Description:
ksh93 dumps core seemingly at random.
>How-To-Repeat:
in a sufficiently large glob request, say
grep stdio */*
watch the core dump. (my example generates a glob list of 194
elements. I don't know the exact repeat parameteres.)
>Fix:
Apparantly, a fix is pending at AT&T. The real problem is in
sfio and/or stak.
Until then, fix the symptoms with the following patch to
src/cmd/ksh93/sh/path.c (which I placed in
files/src_cmd_kah93_sh_path.c):
