That would make sense and also corresponds to what bill lam suggested. As for the whole clear'' thing - there were other ways of getting it to crash when clear'' was not present. I suspect that what we are seeing here has to do with access to uninitialized memory, and it's mostly coincidence what that does, but arbitrary other actions can influence whether or not it yields a crash.
