This is compiler-specific. You may compare given pointer with pointer to a local variable. Result interpretation depends on the way compiler implements heap and stack. Generally, for given compiler, stack pointer is always less (or greater) than heap pointer. In any case, THIS IS BAD DESIGN. This may not work if pointer belongs to another heap (for example, allocated in another Dll).
