Fuzz-testing Dash Core
==========================
A special test harness `test_dash_fuzzy` is provided to provide an easy
entry point for fuzzers and the like. In this document we'll describe how to
use it with AFL and libFuzzer.

The fuzzing can be sped up significantly (~200x) by using `afl-clang-fast` and
`afl-clang-fast++` in place of `afl-gcc` and `afl-g++` when compiling. When
compiling using `afl-clang-fast`/`afl-clang-fast++` the resulting
`test_dash_fuzzy` binary will be instrumented in such a way that the AFL
binary will be instrumented in such a way that the AFL
features "persistent mode" and "deferred forkserver" can be used. See
