That leaves us with the aliasing violations. I looked at the first, and
I couldn't tell why gcc (4.3.4) thinks it is wrong:
safecode/runtime/BitmapPoolAllocator/PoolAllocatorBitMask.cpp:185:
warning: dereferencing type-punned pointer will break strict-aliasing rules
Line 185 is: PS->addToList((PoolSlab**)&Pool->Ptr2);

and Ptr2 is a field of type void*. Isn't void* compatible with anything?

Best regards,
