Depends.

#include <stdio.h>
int main(void) {
_Bool x = 0;
x += 2;
printf("%d\n", x);

It can't "overflow". If that's good or not I can't tell, and I can only
imagine an artifical scenario where it affects things:
void do_something_wrong(int *x) {
*x += 2;
}
int x = 0;
do_something_wrong(&x);
if(x & 1)
printf("x & 1");
>From this one, we would expect nothing to be printed. But if x was a _Bool
x (and _Bool *x, respectively), something would be printed.
