I'm not sure why I received that bug. I'm not part of blink. I work on chrome ios (bling) which doesn't include blink.

Labels: Needs-Feedback
ClusterFuzz testcase 5782001325703168 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.
