you should really use "with" sentence with scoped buffers, otherwise you're leaking memory. Same goes for lltype.malloc(flavor='raw'), you need to lltype.free it.
I don't think that causes crashes though, I would need to take a deeper look into the incantation too. How do I get a crash? Is there a failing test?
