I have marked these tests as failing while this issue is investigated. https://trac.webkit.org/changeset/264730/webkit

Was able to reproduce this crash with command: run-webkit-test imported/w3c/web-platform-tests/webrtc/RTCRtpTransceiver-stop.html imported/w3c/web-platform-tests/webrtc/RTCRtpTransceiver.https.html imported/w3c/web-platform-tests/webrtc/RTCSctpTransport-events.html --debug --child-processes 1 Regression range is 264476 - 264517

It looks like this test started crashing when I skipped multiple webrtc tests in https://trac.webkit.org/changeset/264520/webkit sense this test is reproducible with a test list of 3 tests run in sequence: imported/w3c/web-platform-tests/webrtc/RTCRtpTransceiver-stop.html imported/w3c/web-platform-tests/webrtc/RTCRtpTransceiver.https.html imported/w3c/web-platform-tests/webrtc/RTCSctpTransport-events.html then when I skipped those tests this was the next test in line to crash. This is more fallout from https://trac.webkit.org/changeset/264492/webkit

This affects both iOS and Mac debug wk2. Adding iOS debug wk2 test expectation.

As per bug 215025, imported/w3c/web-platform-tests/webrtc/RTCSctpTransport-maxChannels.html is also crashing.

This appears resolved on iOS, as the only observed issue is the flaky failure reported in bug 230485.

Removed skip expectation on iOS as part of this PR: https://github.com/WebKit/WebKit/pull/26218
