bug? runtime error passing POD

[Daniel Franke]

Hi all,

before filing a bug report I'd like to double check whether this is a bug or 
not (I don't know anything about fortran, I just have to use it).

Synopsis: Pass a single value from C to F90.

The code snipplet below compiles using g77-3.3 as well as using 
gfortran-4.0.1-20050616:

-- f.f --
     1          SUBROUTINE f( n )
     2            integer :: n
     3            print *, "n = ", n
     4          END SUBROUTINE f--
--

To pass a value to fortran-77, one has to provide the address. Assumption: 
plain old data types are handled likewise in fortran-90/gfortran (I know that 
there are array types that aren't).
-- test.c --
     1  void f_(int *);
     2  int main() {
     3          int n = 42;
     4          f_(&n);
     5          return 0;
     6  }
--

Compiling and linking results in:
$>./test.g77
 n =  42
$> ./test.gfortran
Fortran runtime error: End of record


Compiling the same code using SUN's f77/f90 compilers results in:
$>./test.f77
 n =   42
$>./test.f90
 n =  42

Question: Bug in gfortran or misunderstanding on my side?

Thanks

	Daniel
