Until the Valgrind team prioritizes OS X, you can safely assume that it will not give correct results on Apple systems running OS X versions newer than 10.7.

On my Mavericks (10.9.5) machine, I still get the following warning from Valgrind (3.9.0)

WARNING: Support on MacOS 10.8/10.9 is experimental and mostly broken.
WARNING: Expect incorrect results, assertions and crashes.
WARNING: In particular, Memcheck on 32-bit programs will fail to
WARNING: detect any errors associated with heap-allocated data.

For what it's worth, Valgrind 3.10.0 shows no leaks on my Debian Jessie installation.
