Robert Nishihara commented on ARROW-2578:
-----------------------------------------
This is suspiciously similar to
[https://github.com/ray-project/ray/issues/1423,] so I suspect it's a known
valgrind bug and that upgrading to valgrind 3.13.0 would solve the issue.
Did the underlying valgrind version change or something?
