Hi Hazen,
I see ... this is really a problem of the older version of gfortran. I tried
the code below with version 5.4, just to make sure:
module passing_c
use iso_c_binding
implicit none
contains
subroutine pass_array( array )
integer, dimension(:), target :: array
call pass_it( c_loc(array) )
end subroutine pass_array
end module passing_c
and got no error messages or warnings at all.
What happens if you add the bind(c) attribute, like:
integer, dimension(:), target, bind(c) :: array
It is not the nicest solution, but maybe that will solve the problem.
Regards,
Arjen
