Thanks Ioi for making me adding the assert!!! The sequencing of the allocation function and the arguments to the constructor is not what I thought, so my "solution" is not working. I am unsure how to resolve this in a good way. We could probably have a small thread local collection of (type, address) pairs, but I wonder if it is not better removing this debug information altogether. It is to my knowledge only used in GrowableArray (to limit the type of its internal allocations) and to hinder delete on resource allocated objects.
