README.md
To build the fuzzers with libFuzzer to perform actual fuzzing, build with:
CXX=clang++ CXXFLAGS="-fsanitize=address,fuzzer-no-link" meson fuzzbuild --default-library=static -Dfuzzer_ldflags="-fsanitize=address,fuzzer"
ninja -Cfuzzbuild
Then, run the fuzzer like this:
fuzzbuild/test/fuzzing/hb-{shape,draw,subset,set}-fuzzer [-max_len=2048] [CORPUS_DIR]
Where max_len specifies the maximal length of font files to handle. The smaller the faster.
