Description ag.aiston 2013-06-17 22:43:41 UTC 
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.
