Take a look at bug #45902 for suggestions on tuning back cflags to see if it allows compilation.

When these get resolved, then it will work again. In the meantime, -O1 helps me to compile this file. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13850 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15482
bug #54345 should resolved this bug.
seems to be an issue of 'under optimization' :) *** This bug has been marked as a duplicate of 31243 ***
