""" Given an array a[N] of N elements of type T: - Forming a pointer &a[i] (or a + i) with 0 ≤ i ≤ N is safe. - Forming a pointer &a[i] with i < 0 or i > N causes undefined behavior. - Dereferencing a pointer &a[i] with 0 ≤ i < N is safe. - Dereferencing a pointer &a[i] with i < 0 or i ≥ N causes undefined behavior. """ As pointed by by @medhefgo, here we were forming a pointer to a[-1]. a itself wasn't NULL, so a > 0, and a-1 was also >= 0, and this didn't seem to cause any problems. But it's better to be formally correct, especially if we move the code to src/fundamental/ later on and compile it differently. Compilation shows no size change (with -O0 -g) on build/systemd, so this should have no effect whatsoever. |
