[Bug fortran/37794] New: Fortran module overloading regression

[J dot Hogg at rl dot ac dot uk]

If we overload symbols from modules with specific names I can cause an ICE.
Works fine with earlier versions of gfortran and an old build of gcc-4.4.0.

This error occurs with a build of svn version  number 141030

gfortran-4.4  -c -o hsl_of01d.o hsl_of01d.f90
gfortran-4.4  -c -o hsl_of01i.o hsl_of01i.f90
gfortran-4.4  -c -o test.o test.f90
f951: internal compiler error: Segmentation fault
