Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #15 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Even with the #c10 change it looks to be aliasing violation, does it work fine if you compile with -fno-strict-aliasing or use may_alias on the type through which it is read?
