Most likely dup of bug 50763 (see if reverting r180341 or applying patch from http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50763#c12 helps).
no problems with gcc (GCC) 4.7.0 20111026 (experimental)
(In reply to comment #2) > no problems with gcc (GCC) 4.7.0 20111026 (experimental) Closing as dup of bug 50763 then. *** This bug has been marked as a duplicate of bug 50763 ***
