Subject: gdb-rhbz1186476-internal-error-unqualified-name-re-set-test.patch

;; Fix 'backport GDB 7.4 fix to RHEL 6.6 GDB' [Original Sourceware bug

;; description: 'C++ (and objc): Internal error on unqualified name

;; re-set', PR 11657] (RH BZ 1186476).

Comments from Sergio Durigan Junior:

  The "proper" fix for this whole problem would be to backport the

  "ambiguous linespec" patch series.  However, it is really not

  recommended to do that for RHEL GDB, because the patch series is too

  big and could introduce unwanted regressions.  Instead, what we

  chose to do was to replace the gdb_assert call by a warning (which

  allows the user to continue the debugging session), and tell the

  user that, although more than one location was found for his/her

  breakpoint, only one will be used.
