-fomit-frame-pointer segfaults linux build in single-threaded mode. #78

Closed GoogleCodeExporter closed 8 years ago

It's mystic's. because -fomit-frame-pointer should be on with -O3 build,
but it's happened. If I remove -fomit-frame-pointer form NORMAL_FLAGS, than
build with MGTS off working fine. But otherwise build with MGTS off
segfaulted. As bonus I have noted, than if MGTS on, this crush does not
happened.

Investigating now. And I have seen some weird things with compiler flags and
optimizations before. (Check ix86_cpudetect.c:232 some time. Only effects 32 
bit Linux.)

Not sure what's causing it, but I'm turning off -fomit-frame-pointers for the 
moment.
