Predator and CL could not provide any possible suspects.

Using Code Search for the file, "scheduler_worker_pool_impl.cc" suspecting the below Cl might have caused this issue

Thanks!

I wasn't able to reproduce locally.

Latest run shows an unrelated error:

LAST TESTED STACKTRACE ON REVISION 549440

Clusterfuzz is not really able to reproduce this race. The output of new runs is different and has nothing to do with the original error.

ClusterFuzz testcase 5907527741734912 is still reproducing on tip-of-tree build (trunk).

If this testcase was not reproducible locally or unworkable, ignore this notification and we will file another bug soon with hopefully a better and workable testcase.

Otherwise, if this is not intended to be fixed (e.g. this is an intentional crash), please add ClusterFuzz-Ignore label to prevent future bug filing with similar crash stacktrace.

ClusterFuzz has detected this issue as fixed in range 553139:553151.
