But when I run cargo fuzz build -O locally, it completes successfully. It would be much appreciated if someone who knows more about OSS-fuzz could help here. I did try to run the Docker image the build appears to be using directly, but it couldn't be found:
$ docker run -it --rm gcr.io/oss-fuzz/rust-regex:latest bash
Unable to find image 'gcr.io/oss-fuzz/rust-regex:latest' locally
docker: Error response from daemon: manifest for gcr.io/oss-fuzz/rust-regex:latest not found: manifest unknown: Failed to fetch "latest" from request "/v2/oss-fuzz/rust-regex/manifests/latest".
