[Bug fortran/33174] Testsuite: unexpected failures

["dir at lanl dot gov" <gcc-bugzilla@gcc.gnu.org>]

------- Comment #7 from dir at lanl dot gov  2007-08-27 13:12 -------
My programs fail in the save way on MSYS and GYGWIN, but on none of the other
versions of gfortran. 

I tried intrinsic_integer.f90 by hand and it does not fail on my gfortran
version.

Here is the traceback for pr32417.f90 -
