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: unassig...@gcc.gnu.org
ReportedBy: frag...@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:
