RE: Issue with Bash

   Hi Clement,

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

   Regards,
   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
   .This

      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
      Rishita Saha
