haypo: thanks for stating the issue. ISTM that this classifies as an "obscure" bug: you have to use memoryviews, and you need to compare them for equality, and the comparison needs to be "non-trivial", where "trivial" is defined by "both are 1D byte arrays". While this is a bug, I think it still can be fixed in a bug fix release of 3.3, so un-blocking. I also think that as a first step, a specification needs to be drafted defining when exactly a memory view should compare equal with some other object. I can easily provide a specification that makes the current implementation "correct".
