[Bug fortran/37445] Host-associated proc not found if same-name generic is use-associated

[burnus at gcc dot gnu dot org]

Paul, sounds like a bug for you.

 * * *

The problem is that gfortran calls the use-associated (generic or specific)
procedure instead of the host-associated procedure. (The procedure is
use-associated in the specification part of a module).

If the procedure is USEd in the subroutine or in a PROGRAM, all compilers print
an error.

I wonder whether the following is valid:

 module m2
   use, only: s1

All compilers accept this. However, how to read then the following, assuming
that s1 is also a host-associated procedure:

MODULE M2
  USE M1, only: s1
  procedure(),pointer :: procptr => s1

(Note: "procptr => s1" is Fortran 2008 syntax; F2003 only allows "=> null()".)

Actually, I would reject a program if "only:" is specified [or for "use m2,
s1=>s2"], but I have not checked the standard, yet.
