tkent@, could you please help to find an owner for that?
I guess that there is something wrong with constructor of OwnPtr but I'm not familiar with this code.

Adding Merge-Triage label for tracking purposes.

Once your fix had sufficient bake time (on canary, dev as appropriate), please nominate your fix for merge by adding the Merge-Requested label.

When your merge is approved by the release manager, please start merging with higher milestone label first. Make sure to re-request merge for every milestone in the label list. You can get branch information on omahaproxy.appspot.com.
