             Bug #: 52762
           Summary: Firefox 11 segfault with gcc 4.7 (-O3
                    -march=corei7-avx)
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: fragabr@gmail.com


I compiled Firefox 11 source code with gcc 4.7 and the following optimization:

-O3 -march=corei7-avx (for Sandy Bridge, core i7 2700k)

If i use just -march=corei7 it runs fine. GCC bug?

It compiled fine, but it segfaults:
