[Bug fortran/31209] New: wrong code generated with gfortran

[jv244 at cam dot ac dot uk]

With a recent gfortran, the following compiles, but generates the wrong
results:

FUNCTION F() RESULT(RES)
 INTEGER, POINTER :: RES
 ALLOCATE(RES)
 RES=2
END FUNCTION F

SUBROUTINE S1(f,*,*)
 INTERFACE
  FUNCTION F() RESULT(RES)
   INTEGER, POINTER :: RES
  END FUNCTION F
 END INTERFACE
 RETURN F()
END SUBROUTINE

PROGRAM TEST
   INTERFACE
    FUNCTION F() RESULT(RES)
     INTEGER, POINTER :: RES
    END FUNCTION F
   END INTERFACE


   INTERFACE
    SUBROUTINE S1(f,*,*)
      INTERFACE
       FUNCTION F() RESULT(RES)
        INTEGER, POINTER :: RES
       END FUNCTION F
      END INTERFACE
     END SUBROUTINE
   END INTERFACE

   CALL S1(F,*1,*2)

   1 CONTINUE
   CALL ABORT()

   GOTO 3
   2 CONTINUE

   3 CONTINUE
END
