The -U_FORTIFY_SOURCE does not disable stack protection. If the program does a
segmentation fault then ssp isn't on by default for you. Retry
with -fstack-protector-all just to see if it works. I don't think you applied
the gcc-fstack_protector patch. The ssp patch should work for every
architecture (the fpie patch probably doesn't work for x86-64).
