gcc 4.7: -march=corei7-avx bug?

I tried to compile Firefox 11 with gcc 4.7 optimized with:
-O3 -march=corei7-avx (I have a core i7 2700k)
But Firefox segfaults (backtrace provided, although it seems
not very useful):
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52762
If I compile with -march=corei7 it runs perfectly.
Maybe a gcc bug?
How can I help you to debug this?
Thanks!
