The fix:
http://gcc.gnu.org/git/?p=gcc.git;a=commit;h=7e66313066525b0ce38e140e6d9c815e19d119bf

I don't believe the test is quite correct:

+// { dg-options "-std=gnu++11 -D_GLIBCXX_DEBUG_PEDANTIC" }

I don't get the assertion (pre-patch) unless I give *both*

  -D_GLIBCXX_DEBUG_PEDANTIC *and* -D_GLIBCXX_DEBUG
