970
Product: gcc

Status: UNCONFIRMED
Severity: normal

Reduced test case
glm's test suite fails after r13-3378-gf6c168f8 (or its backport
r12-8913-g985a8962) when targeting PowerPC 64 with -mcpu=970 and
-fstack-protector. I reduced it to the attached .cpp file which should return
0, but returns 4 after the given commit. Using any other -mcpu, or passing
-fno-stack-protector, fixes the issue.
