I have marked these tests as failing while this issue is investigated.

Comment 3 Hector Lopez 2020-07-23 09:42:50 PDT 
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
Comment 4 Truitt Savell 2020-07-23 09:49:07 PDT 
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.

I have marked this test as failing while this issue is investigated.

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

*** Bug 215025 has been marked as a duplicate of this bug. ***
Comment 8 Ben Schwartz 2024-03-20 16:41:12 PDT 
This appears resolved on iOS, as the only observed issue is the flaky failure reported in bug 230485.
Comment 9 Ben Schwartz 2024-03-20 17:26:41 PDT 
Removed skip expectation on iOS as part of this PR: https://github.com/WebKit/WebKit/pull/26218
