Description

I hit this assertion very unreliably, but probably a couple of times a week or so. I'm not sure how to come up with a reduced testcase for this unreliable assertion.

Here's the gdb backtrace:

This is the full |bt full| trace.
Note, i have hit this Assertion during Automated Global Topsite Tests and got a Memory Leak Report (Bug 467782)
Note that the code comment says that this can happen if the target thread is dead and that it's better to leak than crash in that case...
I do assume people here see the "PostEvent failed" warning right before the assert, right?

When I hit this assertion, I do see the "PostEvent failed" warning right before it.
