Summary: pobeqfuzz: SkRRect::computeType SkAbort (was: Abrt in sk_abort_no_print)
I don't think it's worth fixing every assert in Skia unless it causes a real issue in a release build.

Labels: Needs-Feedback
ClusterFuzz testcase 5478638991704064 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.
