[Patch, fortran] PR93924/5 - [OOP] ICE with procedure pointer

[Paul Richard Thomas]

This patch fixes PRs 93924/5. It is another 'obvious' patch, whose
consequences are very limited.

I am trying to slip in as many small ready-to-go patches as I can before we
go too far into stage 4. It would be nice to have the patch for PR98573
(posted 23rd Jan) OK'd before the end of the week.

Cheers

Paul
