[Bug fortran/25098] New: better diagnostic needed

[jv244 at cam dot ac dot uk]

using GNU Fortran 95 (GCC) 4.1.0 20051126 (prerelease)  with '-g -pedantic
-std=f95', I get a bad / no diagnostic for the following invalid code:

MODULE M1
CONTAINS
 SUBROUTINE S1(F)
  INTERFACE
   FUNCTION F()
    INTEGER F
   END FUNCTION F
  END INTERFACE
 END SUBROUTINE S1
END MODULE M1
USE M1
INTEGER :: I
I=1
CALL S1(I)
END
