             Bug #: 50612
           Summary: C_FUNLOC takes the wrong address (result variable not
                    function address)
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Keywords: wrong-code
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: bur...@gcc.gnu.org


Based on the discussion at

In the following program C_FUNLOC takes the address of the result variable and
not the one of the function itself.

I have not checked whether the code is valid, but if it is, the function
address should be taken -- and if it is invalid, an error should be printed.


integer function foo() bind(C)
  use iso_c_binding
  implicit none
  type(c_funptr) :: fptr
  fptr = c_funloc(foo) !  takes address of result variable!
  foo = 42
end function foo
