Grep 2.5.1 crashes in Mac OS X 10.4 with ignore case option

[Phillip G. Apley]

If I type the following in bash, sh, or csh I get the same result:

cd ~/Mail/Mailboxes/Local Messages
grep -m 1 -i -h ^Message-ID: -A 1 InboxTmp.mbox/Messages/830076.emlx

I get a segmentation fault.
Then I get a dialog that says "The application grep quit unexpectedly",
and a 'problem report' which I'll show below.

If I take out the -i there is no error.

It only has a problem on a couple of directories so far, but of  
course they're the ones I most care about. In either case, (ignoring  
case or not) before grep dies, it (so far) outputs the same result set.

I've attached the file that causes the problem.

I'm running gnu grep 2.5.1

I tried it feeding input from a file instead of find, and skipped the  
-print0 and --0 and it does the same thing.
