Hi All,

I committed this to 8-branch on 2019-04-24 but not to 9-branch. I have no
record of why I did this.

The patch now requires an additional line,
        && sym->ns->proc_name->attr.proc != PROC_MODULE
to prevent the error message in pr88376.f90 from changing to the less
helpful
Error: Specification function ‘n’ at (1) must be PURE

I propose to commit to mainline and backport to 12-branch unless there are
objections in the next 24 hours.

Cheers

Paul
