Bug description:Generators segfault
Description:
------------
Can't provide a reproduce script yet I'm afraid, but I have a tree of
objects, some of which are generators. I think this segfault is happening
when destroying the tree. The generators are likely to not have finished
iterating at this point.
Program received signal SIGSEGV, Segmentation fault.
