I find it a bit curious that this started on mozilla-inbound 3 days ago and hasn't yet appeared on any other trees.

I'm looking into retriggers starting from https://tbpl.mozilla.org/?tree=Mozilla-Inbound&rev=f5b05c63480d I started with a bunch on https://tbpl.mozilla.org/?tree=Mozilla-Inbound&rev=3a53ee57c736

Given: https://tbpl.mozilla.org/?tree=Mozilla-Inbound&rev=f5b05c63480d (6 of 11 hit this failure) https://tbpl.mozilla.org/?tree=Mozilla-Inbound&rev=30b100f7edbe (0 of 11 hit this failure) I think we have a 2-push regression range: https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=30b100f7edbe&tochange=f5b05c63480d This is far more likely to be a result of layers changes than JS changes, so I'm blaming bug 1077301 and http://hg.mozilla.org/integration/mozilla-inbound/rev/d16adf321576 .

And retriggers on the Windows XP opt reftest on https://tbpl.mozilla.org/?tree=Mozilla-Inbound&rev=d16adf321576 confirm that it's nical's push.

The only answer I have for "what's different about WinXP reftests on mozilla-inbound than WinXP reftests on every other trunk tree?" is that on m-i we use build slaves in a jacuzzi, a relatively small pool of slaves that only do that one job, to massively increase the chances of getting a dep build. b-i doesn't do WinXP tests, fx-team got clobbered by accidentally switching build harnesses, and mozilla-central is prone to clobbers (by way of just not having an objdir around) because it uses the whole slave pool but builds rarely so they get removed to clear space and they get removed because they are too old. So while I wouldn't count on it, one possibility is that we won't see it again on builds which started after I clobbered Windows on m-i at 09:45.

So much for my clobber theory, since that was on a forced-clobber build which started at 12:33

Actually, the reason this hasn't shown up on a tree other than inbound yet is that it originally landed in: https://hg.mozilla.org/integration/mozilla-inbound/rev/d16adf321576 (bug 1077301 comment 41) and was then backed out for B2G bustage in: https://hg.mozilla.org/integration/mozilla-inbound/rev/fe2216810527 (bug 1077301 comment 42) Then it relanded on inbound: https://hg.mozilla.org/integration/mozilla-inbound/rev/197317c196cf (bug 1077301 comment 43) and that relanding hasn't yet been merged to central. So I shouldn't have expected it to be on any other trees, but it will be pretty soon.

FWIW, I just backed out bug 1077301.

I'll look into that before I reland bug 1077301

Looks like bug 1077301 spiked this again...

I backed it out again. Please verify that WinXP has green reftests on Try (with retriggers) before pushing again.
