Unable to find actual suspect through code search and also observing no CL's under regression range, hence adding appropriate label and requesting someone from dev team to look in to this issue.

Thanks!

mpdenton@, just wondering if this change (https://chromium.googlesource.com/chromium/src/+/5cb3a6cd8648c1585a8bd47c8333c5e406476527) is related?

Thank you!
Well, that change essentially landed the fuzzer. I'm not sure what to do about fuzzer timeouts. It seems like they are to be expected for pathologically bad inputs.

Labels: -Reproducible Unreproducible
ClusterFuzz testcase 5876033016037376 appears to be flaky, updating reproducibility label.
Labels: -Unreproducible Reproducible
Please ignore the last comment about testcase being unreproducible. The testcase is still reproducible. This happened due to a code refactoring on ClusterFuzz side, and the underlying root cause is now fixed. Resetting the label back to Reproducible. Sorry about the inconvenience caused from these incorrect notifications.
