Request experiment for modified libfuzzer.

[jhkim19940830]

Hi @jonathanmetzman and @Alan32Liu,

I added modified versions of libfuzzer to test the effectiveness of coverage feedback in libfuzzer. I wish to run an experiment. Could you please help me run the experiment?

/gcbrun run_experiment.py -a --experiment-config /opt/fuzzbench/service/experiment-config.yaml --experiment-name 2023-11-09-libfuzzer-coverage --fuzzers libfuzzer_partial_coverage libfuzzer_no_coverage

Please let me know if this kind of test is recommended to be ran locally. However, when I ran local experiments I had issues with "Corpus not found for cycle" warnings. These warnings seem to be frequent and inconsistent, especially when I run tests with multiple benchmarks and fuzzers. However when I run a local test with a combination of a benchmark and a fuzzer that gave the warning, the warnings disappear. This may not be a critical issue, but it seems to me that when these warnings are related to report with untested pairs. Could you please provide some insight?

Thank you very much :)
