Before committing any solution we first should have understood the cause of the crash. The peculiarity of example is that the argument of ctypes.c_char.from_buffer is a memoryview. With current code we have following chain (the list creates a reference loop with itself):


Using PyMemoryView_FromObject or hypothetical PyMemoryView_FromObjectEx we could get shorter chain:


May be the cause not in current hack, but in memoryview that can't survive with breaking long chain? Or may be we just are lucky in latter case?

I share Martin's doubts about writability in Eryksun’s patch.
