--- Comment #13 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Andrew Pinski from comment #11) > > Without -fno-semantic-interposition, the functions that cause the undefined > behavior is not inlinined so it does not show up there. I should also mention that modref is basically turned off if not doing -fno-semantic-interposition with -fPIC for many exported functions. So the other option to try is -fno-ipa-modref (besides -fno-strict-aliasing). And if those 2 "work", we need to figure out if there is some aliasing violation or GCC is wrong; I am suspecting the code has some kind of aliasing violation.
