Could you send us the script that caused perl to crash?

Same here. :-)

I cannot reproduce the crash myself. What version of Perl are you
using? What is the output of ‘perl -V’ (with a capital V)? What
arguments are you passing to the script? I tried ‘perl test1.pl tmp 1
1% 1’, where tmp is an empty directory.

I still cannot reproduce this. On OS X, it seems I can’t open enough
files to trigger the crash.

Could you try to reduce the script to a small test case that crashes?

Is any other AIX user able to reproduce it?

From @dcollinsn

The requester never provided a minimal or even reproducible testcase, so I'm closing this. Requestor, if you're still having this issue, please respond with a /minimal/ testcase that demonstrates this bug, ideally on a recent (>=5.22) version of perl. Thanks,

Dan Collins
