Unable to provide possible suspect using Predator, CL and Code Search. sugoi@ -- Could you please look into this issue as the crash data from the test case of the Issue 823031 seems to be similar to the issue. Thanks!

The issue is an integer overflow in blink. Nothing to do with SwiftShader. Assigning to eae@, who's the last person to have touched code in that area, so he can assign it to the proper person.

ClusterFuzz testcase 5715203283746816 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.
