Dear HTH,

Apparently this bug was reported years ago, and it was not fixed. There was no
suggestion on how to avoid it either. 

I am not sure why gfortran is not supported by GNU, as it is used heavily in
the computational physics community and gfortran is one of the compilers (the
other is ifort) installed on supercomputers around the world. There are
millions and millions of lines of code depending on Fortran and there are 10s
of thousands of scientists and students using these codes. The only hope to
adopt new (meaning beyond F77 and F90) features of Fortran by the community is
to have compilers that can handle these new features. Why am I wasting time to
write a nice piece of code (in this case a general interpolation routine that
can handle any type of numbers) if in the end I get a compiler internal error.
nagfor can handle it, ifort can handle it, gfortran cannot. And gfortran is one
of the MAIN fortran compilers. So now I have to dumb down my code to the usual
cut-and-paste style, repetition and so on, because I cannot use class(*). 

So I am frustrated. And maybe my frustration will motivate you to fix the
problem.

Thank you,

Gabor
