After a commit around r268758 50+ webrtc tests began crashing on Catalina WK2 Debug and around 20 on WK1 Debug. These tests are flaky and we will see runs with 50+ crashes and runs with 1 failure. history of runs: https://build.webkit.org/builders/Apple-Catalina-Debug-WK2-Tests?numbuilds=50 Example: https://build.webkit.org/builders/Apple-Catalina-Debug-WK2-Tests/builds/7339 This is reproducible on the bots, I am looking to find a test list that can reproduce these to be more specific. Results: https://build.webkit.org/results/Apple-Catalina-Debug-WK2-Tests/r268822%20(7339)/results.html

# Fatal error in: Source/webrtc/rtc_base/operations_chain.h, line 136 # last system error: 0 # Check failed: (&sequence_checker_)->IsCurrent() It would seem like r268758 only changes GPU Process code, which I think is not supposed to be on in tests. But there are no other potential culprits anywhere near.

Speculatively reverted https://trac.webkit.org/changeset/268938/webkit to fix this. Bisection seems to have shown this as the regression point though the commit seems very unrelated
