Description Miguel Gomez 2018-02-08 07:04:19 PST
Varies between pass and crash.

Please do post the backtrace for the crash from the bots. Crash reports are not very useful without a backtrace.
Comment 2 Michael Catanzaro 2018-02-13 20:16:39 PST
It started failing when you added the crash expectation, because that overrode the toplevel expectations. You didn't do anything wrong there IMO, it was just bad luck; I think it's a waste of time to check the toplevel expectations for every change. I've changed our expectation to [ Pass Failure Slow Crash ].

There is never any backtrace:

It's not the only test this happens to. Something is wrong with the bots. (Perhaps it is missing network process crashes, or UI process crashes?)
