Subject: Re: [Fortran, Patch, Coarray, PR 37336] Fix crash in finalizer when derived type coarray is already freed.

Hi Andre,

The patch looks fine to me. Since you mention it in the comment, is it
worth declaring the derived type 'foo' in a module and giving it a
final routine?

Thanks for the patch.

Paul
