Predator, Code Search and CL could not provide any possible suspects.
Adding CF-NeedsTriage for further inputs.
Thank You.

These allocator failures produce very poor report.
Could we add a description of the failure and a stack trace?

Status: WontFix (was: Untriaged)
ClusterFuzz testcase 4515898340933632 is flaky and no longer crashes, so closing issue.

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