+ BASH PATCH REPORT
+ =================
+
+Bash-Release: 3.2
+Patch-ID: bash32-010
+
+Bug-Reported-by: Ryan Waldron <rew at erebor.com>
+Bug-Reference-ID: <20070119065603.546D011E9C at kansas.erebor.com>
+Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2007-01/msg00059.html
+
+Bug-Description:
+
+The glibc implementation of regcomp/regexec does not allow backslashes to
+escape "ordinary" pattern characters when matching. Bash used backslashes
+to quote all characters when the pattern argument to the [[ special
+command's =~ operator was quoted. This caused the match to fail on Linux
+and other systems using GNU libc.
+
