Todd Lipcon commented on KUDU-1426:
-----------------------------------
Oh, I see this is the same commit that Adar just asked about. Can you let us
know the specific hash of master you're buildnig, though, so we can try to
repro? Unfortunately we don't have continuous integration on OSX so
occasionally we get regressions like this on master.
