Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org, | |kyukhin at gcc dot gnu.org --- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Bet this started with r230755, or at least is caused by it. Most of the changes in that commit affect solely Cilk+ gimplification, which is fine, that should only happen during the initial gimplification and not happen later on. Seems Igor has posted a patch that fixes this: https://gcc.gnu.org/ml/gcc-patches/2015-12/msg00651.html , but that patch still looks wrong to me.
