I can reproduce it with groff 1.23.0-HEAD and groff 1.22.4.  So not a
new bug.

Just from eyeballing the behavior, it looks like there is no lower bound
on the size of a "stretchable" ("paddable") space, and there should be.
Or equivalently, the "stretch" should not be permitted to take negative

Thanks for the reproducer.

Looks like this one will need to be scheduled for groff 1.23.1.

Do you have time to file a Savannah ticket for it?
