Instead of pushing the message, file name, line# and function name separately, we now mash the message, file name and line# into a string constant and pass that. This means that the failure path only has to push a single address onto the stack, reducing the code size and causing the compiler to inline many more functions containing an assertions (e.g RefPtr::operator*()) Obviously if you wanted minimal size, you could turn assertions off entirely, but I really like running with assertions, so let's make a little effort to reduce their impact. :^)
