Unable to find the actual suspect through code search and also from the provided CL. But observing  issue 780938  with similar stack has been worked and fixed recently, hence cc'ing @pennymac for more updates on this issue.

Thanks!

This is not the same issue I attempted to fix during fuzzathon, which was blowing the stack due to uncontrolled recursion in special fuzzing inputs.

I don't know anything else about gn_parser_fuzzer, or why it would timeout.

Status: WontFix (was: Untriaged)
ClusterFuzz testcase 6454893901250560 is flaky and no longer crashes, so closing issue.

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