You can't really compare them because Undefined Behaviour is a runtime thing rather than a compile-time thing. Something like `x = *(char*)0;` is legal in a conforming C++ program as long as it's never executed. I vastly prefer UB Sanitizer because it detects a ton of stuff that static analysis can't. But there's plenty of room for both. ------------- PR: https://git.openjdk.org/jdk/pull/11604
