I occasionally see the "Component Manager being held past XPCOM shutdown" assertion, although it doesn't cause a crash under win2k. Any progress or further information on the cause of this issue?
My experience is that the holding of the ref is a side effect of the shutdown ordering between the xpconnect module and the JS component loader module. xpconnect is shutting down first and for reasons too painful to mention it does not automatically do a Release on the wrapped native component manager which it renders uncallable from JS code. There is work afoot to combine the xpconnect and JS component loader modules. I'm not sure this would by itself fix things. There is the question of the proper ordering between the shutdown of the set of component loaders (currently only the native, JS, and Python loaders in our tree) and the modules loaded by the native component loader (such as xpconnect). I sometimes wonder if the assert is necessary. Yes, it is odd that references are held, and any calls made to it after this point ought to return error codes. but is it really so evil to hold the reference? I mostly think it *is* evil. But I wonder if it much matters.

Since this assertion has been around for a year and happens every time I exit a debug build, can it be changed so that only certain people see the assertion?

Comment on attachment 89735 [details] [diff] [review] fix [-uw] xpcshell This patch has nothing to do with the reported problem (an assertion when running the mozilla executable). There is ZERO discussion in the bug to talk about what the patch does or why it might be a good thing. If all you are trying to do is releae the service manager at a specific time then why not add a line to just null it out? The real problem is about the JS component system holding onto the SM too long. Not about the xpcshell. Also note that module owner approval would be necessary before checkin. I don't care *who* you corner on IRC.

I'm going to reopen this. The leaks of the component manager are separate from the leaks of the nsXPCComponents object. (I can fix the former without fixing the latter.) In particular, I see three references to the component manager leaked in my build. * one is a reference held by an XPCWrappedNative, related to the presence of some JS component. When I move all the JS components out of the components directory, this leaked reference goes away. * The other two are related to the Java plugin, which leaks two references to the component manager. I'll attach a refcount balancer tree showing these leaks.

Actually, once I'm not using the Java plugin anymore, I don't see the leaked wrapper related to the JS components either.
(But actually, seeing the world as this leak-free with JS components requires having attachment 117847 [details] [diff] [review] in your tree. Otherwise I do leak the component manager even without the Java plugin, along with a whole bunch of other stuff.)
I also see a leak without either js components or Java installed when you press the "exit" button on the profile manager dialog.

I managed to grab a dump file for a similar stack trace as comment #26. Error happened on m-c 77594:1f800c226837 (2011-06-26 tip) when closing Nightly after a browsing session. Let me know if the dump file will be helpful.
