#2571: runtime failure due to useing character*8 in DECLARE_CCTK_ARGUMENTS_CHECKED macro

Reporter: Roland Haas Status: new Milestone: Version: development version Type: bug Priority: major Component: Cactus

Comment (by Roland Haas):

Changing from `charater*8` to `logical*8` may not be not be enough to avoid assignment. The intel compiler (ifort (IFORT) 18.0.3 20180410) compiles this without warning:

```fortran program foo implicit none

logical*8 :: bar integer*4 :: baz

bar = baz

end program ```

On the other hand we are not worried about assignment to the pointer itself. We want to fails is things like: `bar(1,2,3)` for reading and writing and passing `bar` to a subroutine (which we likely cannot prevent no matter what).

So it should be enough for our purposes.
