Subject Re: Does this mem-tracker.h assertion ring a bell?

Yeah it's probably another consequence of
https://issues.apache.org/jira/browse/IMPALA-5789. Maybe your patch changed
the timing enough to trigger it.

I think the bug might be related to using directory.capacity() as the
argument to Release(). Calling directory.clear() after releasing the memory
in FitlerState::Disable() won't necessarily deallocate the memory so we
could end up releasing it twice.
