[Bug fortran/42072] New: [F03] wrong-code with C_F_PROCPOINTER

[janus at gcc dot gnu dot org]

The following variant of proc_ptr_8.* fails at runtime:


! { dg-do run }
! { dg-additional-sources proc_ptr_8.c }

MODULE X

  USE ISO_C_BINDING
  INTERFACE
    INTEGER(KIND=C_INT) FUNCTION mytype( a ) BIND(C)
       USE ISO_C_BINDING
       INTEGER(KIND=C_INT), VALUE :: a
    END FUNCTION
    SUBROUTINE init() BIND(C,name="init")
    END SUBROUTINE
  END INTERFACE

  TYPE(C_FUNPTR), BIND(C,name="funpointer") :: funpointer

END MODULE X

USE X
PROCEDURE(mytype), POINTER :: ptype

CALL init()
call setpointer(ptype)
if (ptype(3) /= 9) call abort()

contains

  subroutine setpointer (p)
    PROCEDURE(mytype), POINTER :: p
    CALL C_F_PROCPOINTER(funpointer,p)
  end subroutine

END

! { dg-final { cleanup-modules "X" } }


/* Used by proc_ptr_8.f90.
   PR fortran/32580.  */

int (*funpointer)(int);

int f(int t)
{
  return t*3;
}

void init()
{
 funpointer=f;
}
