If you suspect that the result above is incorrect, try re-doing that job on the test case report page.

This is not fixed, just that ClusterFuzz is able to ignore these crashes properly now!. Mac was having missing source paths which now show up and we ignore based on #0 and #1 with mesa is ignored.
