> 1) It doesn't remove these assignments, instead it assigns to 0.
Same thing in reality ...
> 2) No any warning pointing to the unusable assignment.
There is no way for GCC to do that really.
-fsanitize=address -fsanitize=undefined might be able to detect this at
runtime; I have not checked.
> 3) No backward compatibility: worked code now stopped to run.
