Comment 1 Serge Belyshev 2011-10-24 17:57:09 UTC 
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).
Comment 2 Max DeLiso 2011-10-27 00:48:15 UTC 
no problems with gcc (GCC) 4.7.0 20111026 (experimental)
Comment 3 Serge Belyshev 2011-10-27 07:21:11 UTC 
(In reply to comment #2)
> no problems with gcc (GCC) 4.7.0 20111026 (experimental)

Closing as dup of bug 50763 then.
