This is also not caught:

module test
implicit none
interface
   subroutine hello(n)
     integer :: n
   end subroutine hello
end interface
contains
  subroutine bar()
     call hello(3)
  end subroutine bar
end module test

subroutine hello(r)
  real :: r
  integer :: i
  do i = 1, int(r); print *, 'hello'; end do
end subroutine hello

    Test global identifiers against what is specified interfaces.

    Apart from calling gfc_compare_interfaces to check interfaces against
    global identifiers, this also sets and check a few sym->error flags
    to avoid duplicate error messages.  I thought about issuing errors
    on mismatched interfaces, but when the procedure is not invoked,
    a warning should be enough to alert the user.

    gcc/fortran/ChangeLog:

            PR fortran/27318
            * frontend-passes.c (check_against_globals): New function.
            (gfc_check_externals): Split; also invoke check_against_globals
            via gfc_traverse_ns.
            (gfc_check_externals0): Recursive part formerly in
            gfc_check_externals.
            * resolve.c (resolve_global_procedure): Set sym->error on
            interface mismatch.
            * symbol.c (ambiguous_symbol): Check for, and set sym->error.

    gcc/testsuite/ChangeLog:

            PR fortran/27318
            * gfortran.dg/error_recovery_1.f90: Adjust test case.
