Find it and CL did not provide any possible suspects.
Using Code Search for the file "rootinlinebox.cpp" assigning to the concern owner,
@dgrogan -- Could you please look into the issue, kindly re-assign if this is related to your changes.
Thank You.

msrchandra, or someone from the QA team, can you run a per-revision bisect to identify the culprit CL?

dgrogan@, As per the above CF report (https://cluster-fuzz.appspot.com/v2/testcase-detail/5942350904033280?noredirect=1), the test is not reproducible. Not very sure if the per-revision bisect really helps here.

Thank you!

ClusterFuzz testcase 5942350904033280 is flaky and no longer reproduces, so closing issue.

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