"Tautological pointer comparison" build failure(s) — clang 3.4
Incorrect code...#includegcc with -Wall also detects some of these errors but not the one involving NULL.void foo() { int arr[5]; int x; // warn on these conditionals if (foo); if (arr); if (&x); if (foo == NULL); if (arr == NULL); if (&x == NULL); } void f(int &x) { if (&x == nullptr) { } }
