// Example of a standalone runner for "fuzz targets".
// It reads all files passed as parameters and feeds their contents
// one by one into the fuzz target (LLVMFuzzerTestOneInput).
// This runner does not do any fuzzing, but allows us to run the fuzz target
// on the test corpus (e.g. "do_stuff_test_data") or on a single file,
// e.g. the one that comes from a bug report.

// This is a fuzz target that times out on every input by infinite looping.
// This is used for testing.
// Build instructions:
// 1. clang++ -fsanitize=fuzzer TimeoutFuzzer.cpp -o timeout_fuzzer
// 2. strip timeout_fuzzer
// The binary is stripped to save space in the git repo.
