Labels: -Reproducible Unreproducible
ClusterFuzz testcase 4642553212960768 appears to be flaky, updating reproducibility label.
Labels: -Unreproducible Reproducible
Please ignore the last comment about testcase being unreproducible. The testcase is still reproducible. This happened due to a code refactoring on ClusterFuzz side, and the underlying root cause is now fixed. Resetting the label back to Reproducible. Sorry about the inconvenience caused from these incorrect notifications.
The documentation for reproducing on Windows has been moved to https://chromium.googlesource.com/chromium/src/+/master/testing/libfuzzer/reproducing.md
