BASH PATCH REPORT
=================
Bash-Release: 4.3
Patch-ID: bash43-032
Bug-Reported-by: crispusfairbairn@gmail.com
Bug-Reference-ID: <b5e499f7-3b98-408d-9f94-c0387580e73a@googlegroups.com>
Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2014-09/msg00013.html
Bug-Description:
When bash is running in Posix mode, it allows signals -- including SIGCHLD --
to interrupt the `wait' builtin, as Posix requires. However, the interrupt
causes bash to not run a SIGCHLD trap for all exited children. This patch
fixes the issue and restores the documented behavior in Posix mode.
Patch (apply with `patch -p0'):
