Hi Clement,
We have given it a try after applying the patches that you are
referring to. We are still seeing the core dump.

Rishita

Hi Rishita,
Could you try with BullFreeware's version, which have a slightly higher
version (5.0.11 instead of 5.0) ?
You can find it at [1]http://www.bullfreeware.com/pkg?id=5740.
If it's not working, I'll check what's wrong.
Clément

Hi All,
We are using Bash 5.0 (64bit built using gcc ) in AIX 7.2 machine

We are seeing recurring bash core dumps on our servers. Leaving bash
sessions running on the servers for extended periods of time causes
the
core dump (to recreate it, we left httpd running for about a week
and a
half and encountered the core dump). I am hereby sharing the stack
trace of the core so generated.

From the stack trace , it looks like bash is looping in a code that
is
setting terminal attributes in response to a signal, and dumps core
once it runs out of stack.
Any insights will be greatly helpful.
Thanks and Regards
