Gcc-4.7.3 ada (gnat) multilib fails to build with -fopenmp c-cxx flag. Get segmentation faults or errors. Using these flags to build gcc-4.7.3: "-O2 -pipe -msse -msse2 -msse3 -msse4a -msseregparm -mfpmath=sse -fomit-frame-pointer -fopenmp -minline-all-stringops -mno-3dnow -march=bdver2". Ommitting -fopenmp flag from above allows gcc-4.7.3 multilib to build fine however. EDIT: Lost log file. Sorry. Will reproduce the issue when I get time (already reproduced it four times which took a whole day)...
Built fine with fopenmp after installing it without fopenmp... Could very well be my hardware...
Please don't obfuscate the title, it makes searching this bug harder; thank you.
