// is_debug=false is_ubsan_security=true' --check
// ninja -C out/Fuzz blink_png_decoder_fuzzer
//
// Run with:
// ./out/Fuzz/blink_png_decoder_fuzzer
// third_party/blink/web_tests/images/resources/pngfuzz
//
// Alternatively, it can be run with:
// ./out/Fuzz/blink_png_decoder_fuzzer ~/another_dir_to_store_corpus
// third_party/blink/web_tests/images/resources/pngfuzz
//
// so the fuzzer will read both directories passed, but all new generated
