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'):
