Actually, most JIT-based VMs don't do explicit null checks, but rather let the OS signal access violation (as it is supposed to be guaranteed for NULL pointers, unlike dangling or garbage ones), and if it happens, wrap it into the language-specific exception - it's much faster than explicit checks for every pointer dereference. Each argument must be a pointer to a variable of a type that corresponds to a type specifier in format. "Access violation executing location 0x00000010" Since it's trying to execute code at that location the most likely cause is a corrupted stack.
