--- Comment #9 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
For the record the test gfortran.dg/typebound_operator_3.f03 also failed with
-O1 and -m64 (see https://gcc.gnu.org/ml/gcc-regression/2014-09/msg00226.html).
This is fixed by the patch at
https://gcc.gnu.org/ml/gcc-patches/2014-09/msg02568.html.
