No, it's something Dag added to have the compiler notice when temps are
freed multiple times, or freed without being allocated. The crash you
notice shows that there is a problem with the temp (de-)allocation.

However, the reason why you get an AttributeError instead of a meaningful
error message is also a bug.

A stripped-down test case would definitely help here.
