--------------------------------------
If you look at the travis run against the Debug release there's a more accurate
traceback:

This is more accurate since the leaked objects are maintained on a free pool.
The debug build tracks these free pools and records the last point of
allocation from the pool. ASAN only tracks where the object was first
allocated from the heap - not the last time it was allocated from the pool.
I'm afraid that this particular traceback doesn't give us any more info other
than "a received message was leaked" :(
