[Bug fortran/39998] New: Procedure Pointer Assignments: Statement Functions & Internal Functions

["janus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

According to the following passage of the Fortran 2003 standard, statement
functions and internal functions are forbidden in procedure pointer
assignments:

C727 (R742) A procedure-name shall be the name of an external, module, or dummy
procedure, a specific intrinsic function listed in 13.6 and not marked with a
bullet (â?¢), or a procedure pointer.

Test cases:

f(x) = x**2
procedure(), pointer :: p
p => f
print *, p(4.0)
end

**********

 procedure(), pointer :: p
 p => sub
contains
 subroutine sub
 end subroutine sub
end

**********

Internal functions, however, are valid in Fortran 2008.

Thanks to Tobias for reporting this.
