Bug #: 53945
Summary: Scalar element of assumed-shape dummy array not
recognized as C interoperable
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: towns...@astro.wisc.edu
(Reposting from an initial question in comp.lang.fortran):
I'm having trouble getting the following to compile with gfortran 4.7.2:
--SNIP--
program foo
USE ISO_C_BINDING
implicit none
contains
subroutine bar (a)
real, intent(in), target :: a(:,:)
type(C_PTR) :: a_ptr
a_ptr = C_LOC(a(1,1))
end subroutine bar
end program foo
--SNIP--
The error message is:
Error: Assumed-shape array 'a' at (1) cannot be an argument to the
procedure 'c_loc' because it is not C interoperable
This isn't right; although the array 'a' is not
interoperable because it is assumed-shape (but not allocatable), the
*element* a(1,1) is a scalar and thus should be interoperable.
Looks like the same problem as 50269, in a slightly different context.
