This is easily fixed by the following patchlet (I had just forgotten about this
case):

gfc_error ("Interface mismatch in procedure pointer assignment "
"at %L: %s", &rvalue->where, err);
However, there remains one problem (aka PR 39695): The error message for the
code in comment #0 has the wrong name:
p => f()
1
Error: Interface mismatch in procedure pointer assignment at (1): Type/kind
mismatch in return value of 'ppr@'
