This one is the crash we were trying to narrow down in issue 561873, so that is great. I built ubsan but just opening the file doesn't repro. This requires gestures, I need to learn a bit more on clusterfuzz to be able to repro.

ClusterFuzz testcase 4614699749736448 is flaky and no longer reproduces, so closing issue. If this is incorrect, please add ClusterFuzz-Wrong label and re-open the issue. |
