this should hopefully resolve the recent build issue: ``` Step #5: warning: /workspace/out/libfuzzer-coverage-x86_64/dumps/parser.14845295624977050394_0.profraw: unsupported instrumentation profile format version Step #5: error: no profile can be merged Step #5: [2024-02-28 06:09:14,766 INFO] Finding shared libraries for targets (if any).

## Description This will make it easier to debug coverage failures that are not reproducible locally. The failure that I am trying to debug: - https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=62231 - https://oss-fuzz-build-logs.storage.googleapis.com/log-c420cf0c-f073-4c42-b75c-422971ef272e.txt ``` Step #5: Already have image (with digest): gcr.io/oss-fuzz-base/base-runner Step #5: Entering python fuzzing Step #5: Error happened getting coverage of fuzz_parse Step #5: This is likely because Atheris did not exit gracefully ``` Similar log data is displayed in other blocks: https://github.com/google/oss-fuzz/blob/f7165902492d5cff5ee23c018875395061a3bd2b/infra/base-images/base-runner/coverage#L101-L105 https://github.com/google/oss-fuzz/blob/f7165902492d5cff5ee23c018875395061a3bd2b/infra/base-images/base-runner/coverage#L149-L153 https://github.com/google/oss-fuzz/blob/f7165902492d5cff5ee23c018875395061a3bd2b/infra/base-images/base-runner/coverage#L206-L210 https://github.com/google/oss-fuzz/blob/f7165902492d5cff5ee23c018875395061a3bd2b/infra/base-images/base-runner/coverage#L255-L260 --- This PR is a continuation of google#12405 with a renamed branch to avoid trial-build errors: ``` ERROR: (gcloud.builds.submit) INVALID_ARGUMENT: invalid build: invalid build tag "testing-cm/display-coverage-log": must match format "^[\\w][\\w.-]{0,127}$" ``` Co-authored-by: Vitor Guidi <[email protected]>
