This error means the GPU process is exiting for some reason before we record the shutdown leak log, so this bug should live in Core: Graphics. The concern here is that if we are never recording a leak log, then we can't find leaks. This isn't a big deal as long as the failure rate is low, as it is.

Component: DOM: Core & HTML → Graphics

I went and looked at the last 5 or so failures, and it looks like a bunch of process types aren't recording leak logs, so this isn't actually specific to graphics. Maybe we should report a different error for that so that we can find out if the GPU process specifically has leak issues. This should probably be in Content Processes or maybe IPC. This looks to be a problem specifically with web-platform-tests-wdspec-1.
