Well, difficult to say without seeing the source but probably the problem
has nothing to do with the mark function.

ruby is at the end (it will exist) and it call the finalizers : this is the
normal operation.
There are many reasons for such a crash :
* free_MenuSystem() is called twice
* the free function must be called in a predefined order
* ...
Difficult to say more without the source.
