Subject: [Bug fortran/30888]  New: %VAL construct fails with argument procedures
Date: Tue, 20 Feb 2007 17:40:00 -0000	[thread overview]
Message-ID: <bug-30888-11040@http.gcc.gnu.org/bugzilla/> (raw)

When calling procedures which are passed as arguments to
a subroutine the %VAL construct has inconsistent behaviour.
Consider the following code:

      SUBROUTINE VALTEST( DOIT )
      EXTERNAL DOIT
      INTEGER P
      INTEGER I
      I = 0
      P = 0
      CALL DOIT( %VAL( P ) )
      CALL DOIT( I )
      CALL DOIT( %VAL( P ) )
      END

> gfortran -c valtest.f 
valtest.f:9.22:

      CALL DOIT( %VAL( P ) )                                            
                     1
Error: By-value argument at (1) is not allowed in this context

which is an error caused by the second identical call to DOIT(%VAL(P)).
