Hi all, this regression is haunting me a lot in real-world code. It's 'just' a bogus warning, but it can really swamp the output for modules with many private procedures.
I have found a fix that is rather trivial in the sense that it's a
one-liner. However, it may not be as trivial conceptually (in
particular I'm not 100% sure what caused this regression in the first
place; it might have been the the commit for PR40973).
Anyway, it regtests cleanly and fixes the problem as advertised. Ok for trunk?
Cheers,
Janus
