It's not surpising that we overflow the stack when creating 100000 filter elements in one filter.

Labels: Needs-Feedback
ClusterFuzz testcase 4540737638367232 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.

What are you saying. ClusterFuzz. We already have ClusterFuzz-Ignore.
