Mixing functions and subroutines in a generic interface is invalid. gfortran
detects this but the error message is difficult to understand:

Error: FUNCTION at (1) does not belong in a generic subroutine interface

NAG f95:
Error: b.f90, line 10: BAR and SUB must both be SUBROUTINEs or both be
FUNCTIONs for generic GEN

g95:
Error: Interfaces of generic 'gen' at (1) must all be FUNCTIONs or SUBROUTINEs

ifort -stand f95:
fortcom: Warning: b.f90, line 6: Standard Fortran requires that within a
scoping unit, two procedures that have the same generic name shall both be
subroutines or both be functions.   [BAR]

Example:

module mod
  implicit none
  interface gen
    subroutine sub()
    end subroutine sub
    function bar()
      real :: bar
    end function bar
  end interface gen
end module mod
