[Patch, Fortran, OOP] PR 80392: [5/6/7 Regression] ICE with allocatable polymorphic function result in a procedure pointer component

[Steve Kargl]

The patch looks ok to me.  You'll need Release Manager
approval (jakub, richi, or maybe law) to apply the 
patch to the 7-branch.

Hmmm, gcc.gnu.org seems to be unreachable at the moment.
