Note that valgrind can also detect uninitialized reads (or conditional considered uninitialized memory). This is possible with MSan but MSan is a little more challenging to use than ASan+UBSan or TSan. In the years that I've used the sanitizers, I have yet to discover a false positive. It's always been a real bug.
