I have shown the whole output of the doctest failure. What was expected was a traceback ending up with an "AssertionError" message and I got absolutely nothing instead. > I remember noticing planned changes for comparison operators, in > particular between objects that are not in the same class.

I presumably found why I have 2 doctests killed and there seems to be some randomness depending on the tester. It turns out that an object used by llibsingular can be "garbage collected" before we dispose of it with our own disposal mechanism. When that happen the function id_Delete from libsingular is called to free an object on a ring that isn't there anymore...
