--- Comment #3 from Dzianis Kahanovich <mahatma at eu dot by> 2012-07-16 13:15:50 UTC --- (In reply to comment #2) Yes, right, "-O2 -finline-functions" broken too. "-O3 -fno-inline-functions" - broken; "-O3 -fno-inline-functions -fno-ipa-cp-clone" - good. -fno-strict-aliasing and/or -fwrapv - I found no differences in all combinations.
