Fwd: [Bug fortran/54286] [4.8 Regression] Accepts invalid proc-pointer assignments involving proc-ptr function result

[Paul Richard Thomas]

Dear,

I missed the null interface case in the fix for PR54286.  The fix is
'obvious' and 'safe'.

Thanks to Dominique for identifying the problem and the fix.

Cheers

Paul
