My change didn't touch any code (it only removed a DCHECK, and even that not in anything related to this crash), so shouldn't be able to cause this.

Labels: Needs-Feedback
ClusterFuzz testcase 6024007976222720 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.
