--- Comment #34 from Namniav <namniav at gmail dot com> ---
I'd like to provide a more subtle example:
#include <stdio.h>
#include <stdint.h>
int main() {
int a = -1;
int b = -1;
uintptr_t ia = (uintptr_t)&a;
uintptr_t ib = (uintptr_t)(&b + 1);
if (ia == ib) {
*(int*)(ia == ib ? ia : ib) = 42;
printf("%d\n", a);
}
return 0;
}
It prints -1 compiled by gcc -O1 (https://godbolt.org/z/ecf4Kjc16).
