At least one issue seems to be that all your TFPGObjectLists are owners of
their respective instances. This leads to multiple attempted Free() calls
to the objects in the list. If I am correct, there are/will be up to three
Free() calls for some objects in your example code.
I may be wrong, I did not really debug the code, just from looking at it.
