extra tests needed for temporal safety #165
Description
Suppose initial double free has been tested, whether double freed pointers can be reallocated and used to access the same object while writing on it?
Furthermore, whether we can free a non-heap object and add it to the free-list of an allocator? Or, we can free an object of a wrong type, especially this pointer is a derived class using a wrong destruction method? Would this cause different react under different defense techniques?
