Start with fuzz/fuzz_targets/fuzz_common.rs around compare_result and fuzz/fuzz_targets/fuzz_env.rs, where the reported discrepancy occurs. Reproduce the OSS-Fuzz bad-build check for fuzz_env and compare the Rust and GNU env behavior shown in the log. Done means the fuzz target no longer reports a discrepancy and the OSS-Fuzz build passes.
