Created attachment 37010

Fix for the PR

The attached fixes the problem and bootstraps and regtests OK on FC21/x86_64.

Before committing, I want to understand better why the problem is occurring. It
is associated with the finalization routines but I cannot see why at the
moment.

That said, it is obvious that an ARRAY_TYPE should not be sent to any of the
functions that handle descriptors and that this fix cannot do any harm.

Cheers

Paul

PS this makes a nice change from PR54070, where I have a fix for all the
testcase but which fails at any level of optimization :-)

> The code compiles with 5.3.0 and 5.3.1 (r231560). With trunk it compiles

Hence a regression.
