--- Comment #18 from Jack Howarth <howarth at nitro dot med.uc.edu> 2012-12-18 15:15:38 UTC --- (In reply to comment #16) I am puzzled as to why this issue with global-overflow-1.c and stack-overflow-1.c can't be triggered on x86_64 linux. The obvious change of -mtune=core2 seems to be insufficient to cause the failures.
