Created attachment 481253 [details] Build-4663-Log-Output The following layout-tests are constant crashes on macOS Tahoe Debug arm64: imported/w3c/web-platform-tests/encrypted-media/drm-mp4-playback-temporary-encrypted-clear-sources.https.html imported/w3c/web-platform-tests/encrypted-media/drm-mp4-playback-temporary-playduration.html imported/w3c/web-platform-tests/encrypted-media/drm-mp4-playback-temporary-setMediaKeys-after-update.https.html imported/w3c/web-platform-tests/encrypted-media/drm-mp4-playback-temporary-setMediaKeys-immediately.https.html imported/w3c/web-platform-tests/encrypted-media/drm-mp4-playback-temporary-setMediaKeys-onencrypted.https.html imported/w3c/web-platform-tests/encrypted-media/drm-mp4-playback-temporary-two-videos.https.html imported/w3c/web-platform-tests/encrypted-media/drm-mp4-playback-temporary-waitingforkey.https.html imported/w3c/web-platform-tests/encrypted-media/drm-mp4-playback-temporary.https.html imported/w3c/web-platform-tests/encrypted-media/drm-mp4-setmediakeys-again-after-playback.https.html imported/w3c/web-platform-tests/encrypted-media/drm-mp4-setmediakeys-again-after-resetting-src.https.html imported/w3c/web-platform-tests/encrypted-media/drm-mp4-waiting-for-a-key.https.html This is the same set of 11 tests covered by Bug 322840. That bug has been worked through and fixed, but this collection of tests are still crashing and the assertion being hit is different from Bug 322840. Every tests other than 2 has a traceable output that reaches the same assertion failure. The fix for Bug 322840 was addressed in 320124@main which did two things: - removed the assertIsMainThread() call from WebCoreDecompressionSession::invalidate() - deleted the 11 test expectation from Bug 322840 These tests are still expected [ Failure ] from bug 158836 but are constantly crashing even after 320124@main fix. This can mean that a new regression has been uncovered but we cannot currently attribute the regression point to 320124@main.
