ASan Try run has detected that js/xpconnect/tests/unit/test_bug608142.js is failing under ASan. I was able to reproduce this locally with a debug build (mozilla-central 885cde564ff3) by running the following command in the objdir: taskset -c 0 make -C js/xpconnect/tests xpcshell-tests Without the taskset, the bug doesn't reproduce (it seems to be a thread race). I'll attach the symbolized ASan log.
That looks kind of bad. Bug 608142 is "Disallow sending JS objects to a different thread", and in the log something in thread T8 is calling nsXPCWrappedJS::Release() on an object that was freed on the main thread.
Yeah this whole thing is just bad and we should make it go away.
yeah, I'm working on fixing bug 773610. Once we do that, we can rip out all the half-baked thread support.
over to bobby. Can you make sure that someone addresses this when you're done with bug 773610

This is still happening on try: https://tbpl.mozilla.org/php/getParsedLog.php?id=23204529&tree=Try
This test is gone, I'm assuming as part of bholley's work to add runtime aborts for refcounting nsXPCWrappedJS off the main thread, so I'm going to mark this as fixed. I don't think we have any real way of backporting this, unfortunately.
