Consider adding those useful command line options:
- `-jobs=$(nproc)` runs multiple fuzzing jobs in parallel.
- `-jobs=$(nproc)` runs multiple fuzzing jobs in parallel. Note: configuring code coverage profiling with environment variable `LLVM_PROFILE_FILE=deafult-%p.profraw` is required.
- `-rss_limit_mb=0` to ignore out-of-memory issues.
