This one doesn't reproduce on x86_64 Fedora 15 but appears to be a tuning
issue. If I append -mtune=generic to the compilation of
gfortran.dg/class_optional_2.f90 at -O0 on x86_64-apple-darwin12, the resulting
executable runs fine. Likewise, if I append -mtune=core2 to the compilation of
gfortran.dg/class_optional_2.f90 at -O0 on x86_64 Fedora 15, the test case
fails like on x86_64 darwin.
