> Predator was unable to identify any culprit changelists for this test case. > Unable to find actual suspect through code search and also observing no possible suspect CL under regression range, hence adding appropriate label and requesting someone from blink team to look in to this issue. Thanks!

Overflow in setting up painting operations with very large inputs is generally not a problem.

ClusterFuzz testcase 5372067877486592 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.
