+ BASH PATCH REPORT
+ =================
+
+Bash-Release: 4.2
+Patch-ID: bash42-030
+
+Bug-Reported-by: Roman Rakus <rrakus@redhat.com>
+Bug-Reference-ID: <4D7DD91E.7040808@redhat.com>
+Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2011-03/msg00126.html
+
+Bug-Description:
+
+When attempting to glob strings in a multibyte locale, and those strings
+contain invalid multibyte characters that cause mbsnrtowcs to return 0,
+the globbing code loops infinitely.
+
+Patch (apply with `patch -p0'):
