well, I tend to agree about xfails hiding problems away - not a fan either.

However, this problem is not directly related to the test-case (it just happens
to reveal it).

I think we will try to fix this bug - it seems quite serious ... so we could
also decide to live with the test-suite noise?

I think as Jakub mentioned, the _GOT solution will not exhibit this problem.
