InvalidMemoryOperationError generally means that you are 
performing certain disallowed memory operations during a full 
garbage collection, such as allocating while the gc is running.  
This usually happens when you call a function that allocates in a 
destructor, which will trigger this error as the destructor is 
run by the gc.

It appears that the gc issues mentioned above can also trigger 
it.  If you're running off git head, maybe you can apply that PR 
2794 and see if it helps.  Otherwise, maybe you've hit some other 
gc issue somewhere.
