Since bug 673470 landed on mozilla-central, we've been seeing this test failure on Thunderbird's linux 32 builders (VMs). AFAICT this has been permanent on the 32 bit builders. TEST-UNEXPECTED-FAIL | /buildbot/comm-central-linux-opt-unittest-xpcshell/build/xpcshell/tests/toolkit/components/url-classifier/tests/unit/test_partial.js | test failed (with xpcshell return code: 0), see following log: >>>>>>> TEST-INFO | (xpcshell/head.js) | test 1 pending TEST-INFO | (xpcshell/head.js) | test 2 pending running testPartialAdds TEST-INFO | (xpcshell/head.js) | test 2 finished TEST-INFO | (xpcshell/head.js) | running event loop TEST-PASS | /buildbot/comm-central-linux-opt-unittest-xpcshell/build/xpcshell/tests/toolkit/components/url-classifier/tests/unit/head_urlclassifier.js | [null : 184] test-phish-simple;a:1 == test-phish-simple;a:1 TEST-UNEXPECTED-FAIL | /buildbot/comm-central-linux-opt-unittest-xpcshell/build/xpcshell/tests/toolkit/components/url-classifier/tests/unit/head_urlclassifier.js | test-phish-simple == - See following stack: JS frame :: /buildbot/comm-central-linux-opt-unittest-xpcshell/build/xpcshell/head.js :: do_throw :: line 462 JS frame :: /buildbot/comm-central-linux-opt-unittest-xpcshell/build/xpcshell/head.js :: _do_check_eq :: line 556 JS frame :: /buildbot/comm-central-linux-opt-unittest-xpcshell/build/xpcshell/head.js :: do_check_eq :: line 577 JS frame :: /buildbot/comm-central-linux-opt-unittest-xpcshell/build/xpcshell/tests/toolkit/components/url-classifier/tests/unit/head_urlclassifier.js :: <TOP_LEVEL> :: line 198 TEST-INFO | (xpcshell/head.js) | exiting test

Any chance you can run this on a debug build and post the output from the test there? Its quite hard to trace where the problem is for me on a Windows machine, and I don't have a linux machine to test (its also not failing on SeaMonkey Debug afaict)

Might want to log this while you're at it: NSPR_LOG_MODULES="nsChannelClassifier:5, UrlClassifierDbService:5, UrlClassifierHashCompleter:5, timestamp:5, nsUrlClassifierPrefixSet:5, UrlClassifierStreamUpdater:5"

Fwiw: http://mxr.mozilla.org/mozilla-central/source/toolkit/components/url-classifier/tests/unit/test_partial.js

This might be a compiler bug: https://bugzilla.mozilla.org/show_bug.cgi?id=669410#c67

Ok, I did a try build with: MOZ_OPTIMIZE= in toolkit/components/url-classifier/Makefile.in and xpcshell-tests passed. Therefore this is a compiler bug that's been exposed. gozer/jhopkins: we need to update our gcc on the Linux 32 builders to 4.5 (which is already on there) but include all 3 patches currently on the Firefox builders. RelEng have a rpm to do this apparently.

gcc-4.5 rpm being rebuilt with the patches right now.

Updated gcc-4.5 RPM deployed to linux32 build machines.

Ftr, I checked from "Tue Feb 14 00:04:10 2012 PST". Perma-orange, until "Wed Feb 15 13:34:41 2012 PST": 1st build fails, 2nd build succeeds. Since then, a few random oranges: "Wed Feb 15 18:05:06 2012 PST": 2 on momo-vm-fedora12-05 "Thu Feb 16 14:23:56 2012 PST": 1 on momo-vm-fedora12-04 "Fri Feb 17 09:25:02 2012 PST": 1 on momo-vm-fedora12-04 "Fri Feb 17 20:28:28 2012 PST": 1 on momo-vm-fedora12-05 "Mon Feb 20 14:22:53 2012 PST": 1 on momo-vm-fedora12-03

[Triage Comment] untracking this for firefox13, please re-nominate if there's a case here.
