			     BASH PATCH REPORT
			     =================

Bash-Release:	4.3
Patch-ID:	bash43-035

Bug-Reported-by:	<romerox.adrian@gmail.com>
Bug-Reference-ID:	<CABV5r3zhPXmSKUe9uedeGc5YFBM2njJ1iVmY2h5neWdQpDBQug@mail.gmail.com>
Bug-Reference-URL:	http://lists.gnu.org/archive/html/bug-bash/2014-08/msg00045.html

Bug-Description:

A locale with a long name can trigger a buffer overflow and core dump.  This
applies on systems that do not have locale_charset in libc, are not using
GNU libiconv, and are not using the libintl that ships with bash in lib/intl.

Patch (apply with `patch -p0'):
