Hi Emmanuel,

===========================================================
Thanks for the quick reply.  I did a machine reset and started again from make clean.  The failure is consistently repeatable.

The only other updates I've done at all recently were on different machines and up to Feb 9 2022.  I'll try the current commit with a second machine and get back with you.  It will be an i5 running Ubuntu 20.04.  Just to note, I did a "git pull" after a make clean.  I haven't tried a clean, from scratch, install.
