Assigning mvstanton@ to take a look, since CF bisected it to that CL, and the test has splice in it. Did not reproduce with my ToT debug build with the provided gn args, but did not try the clusterfuzz reproduction script due to an authentication issue.
Status: WontFix (was: Assigned)
The CL was re-submitted a month later with important changes. I think we can just close this one.
