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'):
