Debug asserts from the fuzzer in Skia are generally WontFix.  This one looks like it handles resetting to a count of zero even though it asserts.  If there's a release issue, then we can fix it there.

sgtm- you're right code looks like it resets to zero though the assert is there

Labels: Needs-Feedback
ClusterFuzz testcase 5178049598586880 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.
