--- Comment #6 from David Malcolm <dmalcolm at gcc dot gnu.org> --- Thanks; let's keep using this PR for the stuff in comment #5. I've been looking at these on gcc211 in the compile farm: * I see out-of-bounds-diagram-11.c failing as you describe (the overflow in test6 isn't reported with g++ for some reason; it is for gcc) * out-of-bounds-diagram-3.c gets skipped on that machine due to { dg-require-effective-target lp64 } "check_cached_effective_target lp64: returning 0 for unix" Is there a config/cfarm machine you see the out-of-bounds-diagram-3.c failure on?
