Details:

I got a seg fault while doing some routine greping.  Since I don't start
using a large amount of memory, I figure this is not the sort of bug that was
warned about in the man page.

The original command I ran was:

cat ~/segFault.list | grep -P '^\.\/[^/]+\/[^/]+$'

However, I've narrowed it down to
grep -P '[^/]*'
(or grep -P '[^/]+'
 or grep -P '[^/]{2,}
 etc)
None of these do quite what I would expect them to in perl.

grep --version yields:
grep (GNU grep) 2.5.1

System: Fedora Core 3 (or Core 2)
Bash: GNU bash, version 3.00.14(1)-release (i386-redhat-linux-gnu)

Reproduced on a number of different machines (all running grep 2.5.1)...sorry
this is the only version I have access to.

If I missed something important that needs to be known...just ask.

Manfred
