It works, if one changes the scalar coarray into either an array coarray or into a noncoarray scalar. I think gfc_has_alloc_comps just needs to be updated to handle coarrays, which use an array descriptor but aren't true arrays. (I think GFC_TYPE_ARRAY_RANK(...) == 0 can be used to detect this, but that might not work for all array types.) I marked it as "OpenMP" as it is probably also possible to trigger this for some OpenMP code. Even though, I do not have a test case.
