First failure is here: https://ci.chromium.org/buildbot/chromium.memory/Linux%20Chromium%20OS%20ASan%20LSan%20Tests%20%281%29/27975

Unfortunately is has a huge blamelist. I'm guessing this might have been exposed by https://chromium-review.googlesource.com/c/chromium/src/+/1104799 which moved the tests around.

It fails by hitting this DCHECK: https://cs.chromium.org/chromium/src/components/viz/host/host_frame_sink_manager.cc?rcl=f05b09a52f16f5ecf5e23e9b71c505d4915e8d12&l=298

Okay, this is  bug 807465 . I guess the filter entry [1] now needs to be somewhere else?

[1] https://cs.chromium.org/chromium/src/testing/buildbot/filters/viz.browser_tests.filter?rcl=f05b09a52f16f5ecf5e23e9b71c505d4915e8d12&l=3

I don't think this is a dupe; the other bug is about a different bot.

I can believe that https://chromium-review.googlesource.com/c/chromium/src/+/1104799 caused the bug here; I don't think it has anything to do with the other bug.

I think the bug is that my CL added ../../testing/buildbot/filters/browser_tests_cros_asan.filter instead of ../../testing/buildbot/filters/viz.browser_tests.filter as --test-launcher-filter-file. If you change that and re-run testing/buildbot/generate_buildbot_json.py I think the bot will be happy. (The current filter file is unused; kylechar has a CL in flight to remove it.)

I can do this myself in a bit under 2 hours. Maybe you can get to it before me.

CL is https://crrev.com/c/1104967.

The following revision refers to this bug:

Remove CrOS ASan filter files.

The tests disabled by these filters are disabled by DISABLE_ macro,
don't exist or are disabled in a different filter file already.
