Automatically adding ccs based on suspected regression changelists: Refactor checks to use a copy of the new logging backend. by jonasolsson@webrtc.org - https://webrtc.googlesource.com/src/+/f8e5c110ee806992f4092220339939fe5c2d3cc9 If this is incorrect, please let us know why and apply the Test-Predator-Wrong-CLs label.

This looks like a false positive. Both the crash and original stacktrace correctly aborts after a DCHECK fails. It's reported as an abort on unknown address, probably because the check code has been changed slightly. @aleloi: What's the sensible thing to do here? Do we need to register the new abort() address somewhere?
