It is not big and has also radius on it. I had a case, where it does sometimes work. So i think that is really a good/better sanity check test case.

Interestingly, if you change the Overlap property to Overlap mode the second instance works but the third (and following if set to a higher number) doesn't. My example is based on the minimal one posted by chrisb but the same happens with the other

Thanks for the report. Here is the issue: https://github.com/FreeCAD/FreeCAD/issues/6641

When you mean the bug with the 3 occurrences? Here is the link to the bug + bugfixes (i am a little bit in a hurry, if you need something tested, i can a test it, but not asap).

Just looking at the behavior and the text of the commit:

- Use fuzzy fuse/cut method with tolerance Precision::Confusion()

This one change seems to be the culprit.

EDIT: I should just clarify it's purely my speculation.
