We have been trying to track these down as they block the fuzzer from progressing. It's possible there is a solution we can do in code depending on what is happening.
Status: WontFix (was: Available)
Bulk-WontFixing these bugs. This was a bug on ClusterFuzz side, see bug 717534. We will start seeing new testcases auto-filed in a day or two. We can't leave these open as ClusterFuzz won't autoverify them after ClusterFuzz-Wrong label.
Labels: -ClusterFuzz-Wrong
We have made a bunch of changes on ClusterFuzz side, so resetting ClusterFuzz-Wrong label.
