Hello,
AFL engine has separate heap that is entirely freed and destoryed
(HeapDestroy) after AFL formula execution ends
so entire memory is given back to Windows.

just a follow up question on gSite.Free(). does ab always return
memory to the heap space, or does ab cache/manage the free memory itself?

Hello,
If you do not return them from inside of the function, you should
free
them using gSite.Free().
If you forget to do that, they will still be freed automatically
at the
end of formula execution.
Generally speaking everything is freed at the end of formula
execution
(with the exeception to static variables).

gSite.AllocArrayResult(); to create arrays for internal
computations does that also get freed? Or should i allocate that
memory myself and free it before the function returns?
