This has been around for a long time (= months, maybe more): now that we have +/- fixed all the persistent leaks, it's time to look into the intermittent ones. http://tinderbox.mozilla.org/showlog.cgi?log=Firefox3.1/1234576995.1234582226.32611.gz WINNT 5.2 mozilla-1.9.1 unit test on 2009/02/13 18:03:15 TEST-UNEXPECTED-FAIL | runtests-leaks | leaked 286918 bytes during test execution http://tinderbox.mozilla.org/showlog.cgi?log=SeaMonkey/1234559348.1234564505.23529.gz Win2k3 comm-central dep unit test on 2009/02/13 13:09:08 TEST-UNEXPECTED-FAIL | runtests-leaks | leaked 300926 bytes during test execution (threshold set at 200 bytes) I have also seen it 1+ time(s) on my local Windows (1.9.2 trunk) SeaMonkey, so I do not think this is 1.9.1 branch only.

We just hit a cluster of 4 of these, but the leak looks just like the others reported here. http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1240594539.1240603566.21826.gz WINNT 5.2 mozilla-central unit test on 2009/04/24 10:35:39 http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1240594539.1240599884.16639.gz OS X 10.5.2 mozilla-central unit test on 2009/04/24 10:35:39 http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1240598603.1240604371.22881.gz OS X 10.5.2 mozilla-central unit test on 2009/04/24 11:43:23 http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1240599833.1240605196.23988.gz OS X 10.5.2 mozilla-central unit test on 2009/04/24 12:03:53 This would be easier to debug if the leak-checking stuff also set the environment variables needed for and checked the output of leak-gauge.pl, since then we'd know what page was leaking.

So I can't quite figure out why that test would leak intermittently... I wonder whether doing the finish() async instead of from inside the ctor would help. Well, that and we should fix the actual leak....
I wonder what has changed recently because this seems to happen pretty often nowadays. Bug 419527 landed long time ago.
Attached patch patch (obsolete) — — Splinter Review
This seems to fix the leak at least locally. I could commit this one and file a new bug to fix the leak.

This should fix it, hope somebody can check whether it does - I don't see a leak either way (could be due to outdated code base).
