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! -- Linux 3.3.0: Saber-toothed Squirrel http://www.youtube.com/DanielFragaBR
