Tomcat, this is pretty explosive on bughunter. Do you have time to find the regression range and possibly a test case?

This is a pretty low-frequency intermittent dating back to 3 months ago. I would expect bisection to be a pretty big PITA at this point.

Our resident GC gurus might be interested to know about comment 16, though.

We've hit this over 5000 times for almost 1000 urls on Windows. It first appeared in bughunter on 11/3 though the windows workers were almost idle waiting for the osx workers to catch up. Regardless, this is pretty recent for us.

Here's a run that should be able to reproduce the crash based on comment 0. We'll see how many retriggers it takes to see how practical bisection will be. https://treeherder.mozilla.org/ui/#/jobs?repo=try&revision=ed58109d5029

This is happening because ContentChild::QuickExit() is calling exit() regardless of what state the program is in. Global destructors are called and these trigger this assertion because we are destroying a vector while it is currently being modified. Basically doing a quick exit like this is not really valid, and I'm sure there are other manifestations of this problem elsewhere in the system. Some possible solutions, none of which are particularly appealing: - don't use global state that will be destructed when we do a quick exit - have quick exit set some flag to suppress assertions in destructors - implement quick exit in a way that doesn't call destructors

I suppose this isn't really a fix, but going forward we shouldn't be calling this quick exit in debug builds as much any more. Part of my ongoing work on getting leak checking working on e10s is making it so we don't QuickExit() on shutdown in debug builds, because that prevents us from getting leak logs.

Since I don't suppose quick exit is going to go away, we can just create the helper thread state in such a way that it won't get destructed in the case. Still kind of unfortunate. I took the opportunity to remove some calls to ensureInitialized() since this always gets initialized when we create a runtime, and moved the initialization to the runtime since it doesn't just concern the GC.

Comment on attachment 8535047 [details] [diff] [review] bug1051822-helper-state Review of attachment 8535047 [details] [diff] [review]: ----------------------------------------------------------------- I guess the purpose of this lazy init was for faster startup. We're using enough threads for common tasks now that it's not clear if its worthwhile anymore and the situation certainly isn't going to get better going forward.

Comment on attachment 8535047 [details] [diff] [review] bug1051822-helper-state Approval Request Comment [Feature/regressing bug #]: Bug [User impact if declined]: I don't think this actually has any user impact. It's a debug assertion that fires while we are already exiting, so the impact is the test failures we see. [Describe test coverage new/current, TBPL]: This has been on central for 7 days. [Risks and why]: Low [String/UUID change made/needed]: None
