For any bugs, you often have a clue as to what might be going wrong. 
Why would you think that having wraparound on integer overflow helps 
that?  It may change the effect of the bug (or may not - wraparound is 
common behaviour for integer overflow in C.  It's just not guaranteed). 
It is not going to make it easier to detect, just different.  And it is 
going to stop any chance your tools have of detecting it.

I don't normally overflow unsigned types either.  Neither the compiler 
nor sanitizers can help catch such bugs, if they do occur - that makes 
them harder to find.

Perhaps you think I write my code by random and rely on tools to find 
the bugs.  I don't - but where there are tools available, I use them as 
aids.

Yes.

The fact that it is not UB does not help - it is still wrong.

Agreed.

It is merely a common example of undefined behaviour that /could/ be 
defined behaviour, and that some people think /should/ be defined behaviour.

I notice that people who get their knickers in a twist about how 
terrible C's undefined behaviour is, and how signed integer overflow 
"obviously" should wrap, stay rather quite about access via invalid 
pointers, using function pointers that are not correct, or other kinds 
of undefined behaviour.

The language does not make a fuss.  It simply says that nonsensical 
signed integer overflow does not have a meaningful result in C.
