           Summary: Internal compiler error for Fortran files when
                    specifying a file instead of an include directory with

gfortran produces an internal compiler error when one mistakenly specifies a
file instead of a directory with -I:

#> touch file.h
#> touch src.F90
#> gcc-4.9 -I./file.h src.F90
Warning: "./file.h" is not a directory
f951: internal compiler error: Aborted

Happens both withe shipped gcc-4.8.1 from openSUSE 13.1 and
their gcc-4.9.0 from a development repository:

#> gcc-4.9 --version
gcc-4.9 (SUSE Linux) 4.9.0

I could also trigger this with versions 4.8.1, 4.7.3, and 4.6.4, - but not with
4.3.4 :)
