Frequent LSan DNS leaks in WPT tests
Bug 1354232 is about getting WPT tests working with LSan. The most common leaks that seem to show up involve DNS. The leak seems to involve a NetAddrElement, an AddrInfo, and an mHostName string. See the attached file for stacks. This has also showed up for our existing tests, in bug 1400161, but not as frequently. I'm not sure why that is.
We've also got some issues in bug 1423945 that might fix this.

Andrew, do the leaks still happen?
(In reply to Valentin Gosu [:valentin] from comment #2) > Andrew, do the leaks still happen?
You need to remove the DNS-related entries from https://searchfox.org/mozilla-central/source/testing/web-platform/meta/__dir__.ini#1 and do a try run (or otherwide run the tests in an asan build) to find out (or you can examine the log files from an exisitng run for EXPECTED-FAIL with those entries).
Thanks! I'll check!

This started to fail on autoaland. I've created a new bug for this wpt7 failures. Please take a look.
Thanks for filing a separate bug. I think this is due to me removing the Init from the method list. It seems that was suppressing a bunch of other leaks. I'll try to handle it in bug 1497947.
