Automatically assigning owner based on suspected regression changelist https://chromium.googlesource.com/v8/v8/+/0ac7a48ae8c6dbfd1dd4c9e6d5cd4b1a8bd72fe1 ([foozzie] Add slow-path correctness fuzzing variants).

If this is incorrect, please let us know why and apply the Test-Predator-Wrong-CLs label. If you aren't the correct owner for this issue, please unassign yourself as soon as possible so it can be re-triaged.

This was incorrectly minimized and hence incorrectly bisected. The output without minimization is:

# V8 correctness failure
# V8 correctness configs: x64,ignition:x64,slow_path_opt
# V8 correctness sources: f6e
# V8 correctness suppression:

Wrong test case. Fixed by:
https://chromium.googlesource.com/v8/v8/+/f24b9271de9815677d499fe4ceb4e69861d8539d

ClusterFuzz testcase 6719975574994944 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.
