[Bug c++/15496] New: Would like a check for integer overflow

[schnetter at aei dot mpg dot de]

I would like a command line options that inserts checks for integer overflow.  
That is, I would like a run time error whenever and int wraps around.  I know 
that this might be expensive, but it would be very helpful for debugging.
