Description Ben Schwartz 2023-09-29 19:17:54 PDT

The following tests under http/wpt/mediarecorder/ are constantly crashing:

http/wpt/mediarecorder/MediaRecorder-dataavailable.html
http/wpt/mediarecorder/MediaRecorder-multiple-start-stop.html
http/wpt/mediarecorder/MediaRecorder-requestData.html
http/wpt/mediarecorder/pause-recording.html

REPRODUCIBILITY:

I was able to reproduce this issue on macOS Sonoma (14.0, 23A344/arm64) ToT using the following command: 

run-webkit-tests --clobber-old-results --verbose http/wpt/mediarecorder/MediaRecorder-dataavailable.html http/wpt/mediarecorder/MediaRecorder-multiple-start-stop.html http/wpt/mediarecorder/MediaRecorder-requestData.html http/wpt/mediarecorder/pause-recording.html http/wpt/mediarecorder/record-96KHz-sources.html

REGRESSION:

I was able to bisect a possible regression point at 268433@main. This issue did not reproduce before then, and changes at that point appear to be directly related to the issue.
