Yep, also found this to be the failing test and suspected apt
2.1.19/2.1.20 as the culprit. Especially "Forbid negative values in
unsigned StrToNum explicitly" of 2.1.19 looked suspiciously related.

Will test, thanks!

I'm glad about your reply definitely.

Apology accepted. :-)

Actually, when I read that changelog summary, I just thought "Wow!" So
please please keep on that work! Better late than never! :-)
