Without knowing the actual error code that is triggering the failure, it's hard to know what the issue is.
This is unexpected, but isn't severe; we'll fail gracefully in release builds.

I don't see the cycle collector or any DOM code in the assertion stack. This is some MSCOM thing.

Aaron, maybe you could take a look? Thanks.

Actually, that bug is just for cppunittests. But we still need good call stacks. I guess I'll go look at the other occurrences and see which ones are good.

Those assertions and crashes started in September last year. So maybe it's a regression as introduced by bug 1489317, which touched this code?

Bug 1489317 was an important correctness fix, and upon further review of what we did there, everything still looks right to me. The best way to solve this would be to surface the actual error code that is raising the assertion.
