There's a new from a Microsoft security guy, David LeBlanc:
http://blogs.msdn.com/david_leblanc/
<http://blogs.msdn.com/david_leblanc/>  . The inaugural entry is about
this:

	void declspec(noreturn) SafeIntOnOverflow()
	{
	   RaiseException( STATUS_INTEGER_OVERFLOW,
EXCEPTION_NONCONTINUABLE, 0, 0 );
	}

If you're doing vulnerability research on new Microsoft code you need to
read about this.
