Funny how arguing about UB shows that even compiler writers can miss when they are juggling with lots of sharp objects :) There is no way you meant to write integer pointer value - 4 if your intent was 'next to it'. And double the fun is that some future hardware may do sizeof(int) == 1 and have it running 'just fine' :)
As gamedev engine person doing bugs all the time I wish we had some middle ground but a lot of smart people do not want to find it. I guess it is cheaper that way when we just build on the existing C code and hope for the best.
