Patch for GDB checked in on master:
http://www.sourceware.org/ml/gdb-patches/2013-09/msg00370.html

The same problem was detected in GDBserver as well. Fixed on master:
http://www.sourceware.org/ml/gdb-patches/2013-09/msg00381.html

GDBserver fix on the gdb_7_6-branch:
http://www.sourceware.org/ml/gdb-patches/2013-09/msg00449.html

And finally, GDB patch backported to the 7.6 branch:
http://www.sourceware.org/ml/gdb-patches/2013-11/msg00782.html

So, the problem should now be fixed in the upcoming GDB 7.6.2 release.
