This is almost certainly not an issue with IPC.  Please find someone else for triage.

I don't think it can be related to my change above. The thing in common between this bug and  issue 634801  is the view bounds and coordinate conversions. I will take a look at this later.

Also cc-ing kenrb@ for some input on potential issues.

Status: WontFix (was: Assigned)
ClusterFuzz testcase 5058662892830720 is flaky and no longer reproduces, so closing issue.

If this is incorrect, please add ClusterFuzz-Wrong label and re-open the issue.
