Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #11 from Jakub Jelinek <jakub at gcc dot gnu.org> --- If it is really a buffer overflow in cp_gimplify_expr (which is weird, there aren't many arrays in there nor anything else that could result in that, there is tree *data[4] = { NULL, NULL, NULL, NULL }; but you aren't compiling with -fopenmp and it also uses just those 4 entries), then perhaps asan built gcc might be more reliable at detecting it. Of course, if it is miscompiled cp_gimplify_expr, it might be something else...
