Thank you so much! The fuzz wrapper is unbelievably clean, TIL about --run_under.
Will look into stat merger fuzzing issue discussed offline https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=21460

Support for coverage with clang in Bazel was half working because the report produced was in a binary format and it wasn't be utilized by the LCOV merger and therefore didn't show up in the final LCOV report. This CL uses llvm-cov as was used by Envoy in envoyproxy/envoy#10909 to produce an LCOV report. To run this the following environment variable and build flags are needed: BAZEL_USE_LLVM_NATIVE_COVERAGE=1 GCOV={path to llvm_profdata} CC=clang \ BAZEL_LLVM_COV={path to llvm_cov} bazel coverage --experimental_generate_llvm_lcov PiperOrigin-RevId: 338254344
