ksh93 dumps core seemingly at random.
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
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.)
Over to maintainer(s)
I just received the following patch from David Korn. It appears to fix
the problem. I don't kow if you want to install this patch or just wait
for another release of the sources. I did not get any indication from
him about timing of a new release.
I committed David's patch. Thanks for resolving this!
