Status: WontFix (was: Assigned)
Based on discussion with security team and other TLs we've decided not to fix int overflows that aren't considered security issues unless they appear in the wild.

Labels: Needs-Feedback
ClusterFuzz testcase 5706449110171648 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.
