Please stop posting on this topic! I know it is one of your hobby 
horses, but frankly, it seems to be a topic you do not understand 
it at all.

Did you even read that page?

"To help developers detect integer overflows, we created IOC (by 
modifying Clang) to dynamically detect most of C/C++'s integer 
undefined behaviors. "

The key phrase is *undefined behaviors*. Remember that C does not 
require twos-complement arithmetic. D does, so it doesn't have 
those problems in the first place.

It must have been a dozen times by now that you have posted the 
same misinformation over and over again, with links to papers you 
have apparently not read.
