I think this is a known problem, which won't be fixed.

If I read http://gcc.gnu.org/ml/gcc-patches/2007-02/msg00735.html
(plus referred/follow up emails) correctly,
one can replace -g by -gdwarf-2 - then it works.

For the test suite, one could do so, e.g., in
gcc/testsuite/lib/fortran-torture.exp and .../gcc-dg.exp.
