Indeed, this works fine. Thanks a lot for extending the test suite.

These don't work yet with the last patch series. I'll recheck once I
have finished updating the patch series and in particular fixed the
segfault you mentioned earlier.
I hope to be able to send an updated patch series tomorrow.
Do I understand correctly that I can just drop my patch adding the test,
since this is now already covered in a better way by the test case added
in your second patch?
