Hi,

For example in GCC,
char* ptr = (myClass.getObject()).getAddress();
The ptr cannot be used as the object returned by getObject would have been
destroyed and the ptr is invalid. This works find in CC as the copy
constructor is invoked.

I wanted to find such runtime errors. Or in other words Compiler dependent
code.
