Labels: Fuzz-Blocker ReleaseBlock-Beta M-72
This crash occurs very frequently on linux platform and is likely preventing the fuzzer attekett_surku_fuzzer from making much progress. Fixing this will allow more bugs to be found.

Marking this bug as a blocker for next Beta release.

If this is incorrect, please add ClusterFuzz-Wrong label and remove the ReleaseBlock-Beta label.

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!

As per the latest CF report (https://clusterfuzz.com/testcase-detail/4962873107021824) it's not impacting M72. So removing the blocker label.
