Sorry, I responded to Andreas and Christophe in an off-list email 
earlier today.

Basically I temporarily dropped the ball because of the US Thanksgiving 
weekend, but am back on this bug.  I have created PR78566 to reflect 
this, and have CC'ed both of them.

I have a pretty good idea what's going on, and should have something 
tomorrow.
