Patch-ID:	bash43-035

Bug-Reported-by:	<[email protected]>

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'):
