Will look at it. bug 1898476 is Wayland only, the code is not executed on X11 so I wonder how it can affects linux1804-64-asan-qr which doesn't use Wayland at all.

Is there any way how to run the test locally?

Flags: needinfo?(stransky) → needinfo?(nfay)

I don't see a connection to Martin's changes. The test's result changed from ERROR to CRASH - the expectation could be updated if there is no progress in this bug.

Regression range

Backfills point to the landing of bug 1896054 and bug 1874689 as having started this.

I don't see a connection to Martin's changes. The test's result changed from ERROR to CRASH - the expectation could be updated if there is no progress in this bug.

I'm looking at the logs and I dont see this ERROR that you mention?

Is the problem that we have 12982 hanging out at shutdown and we kill it which is seen as a crash?

Flags: needinfo?(aryx.bugmail)

Sorry, there are multiple intermittently crashing trusted-types tests and the first one I checked had ERROR as expected result while the oldest has OK as expected result.

Yes, the shutdown hang (which causes the termination of the application and gets detected as crash) is the new issue.

Especially orangefactor shows only spikes on 10, 11, while we backed out bug 1874689 only on the 16th, so it is likely it was not the cause.

No longer blocks: 1874689
