Somewhere between early June and lastest 8.x, -fprofile-generate broke
on i386. This looks to be related to stack protection.
$ echo 'int main() { return 0; }' > x.c
$ cc x.c
$ cc -fprofile-generate x.c =20
/usr/lib/libgcov.a(_gcov.o)(.text+0x13df): In function `gcov_exit':
/usr/src/gnu/lib/libgcov/../../../contrib/gcc/libgcov.c:532: undefined refe=
rence to `__stack_chk_fail_local'
A friend reports that it works on amd64 from last weekend.
Has anyone else seen this?
