Fuzzing

Requirements:

clang.
libFuzzer: https://github.com/google/fuzzing/blob/master/tutorial/libFuzzerTutorial.md

Compile one of:

clang++ -g -std=c++17 -fsanitize=fuzzer fuzzer/b_plus_multimap_fuzzer.cc -I.
clang++ -g -std=c++17 -fsanitize=fuzzer fuzzer/b_plus_map_fuzzer.cc -I.
clang++ -g -std=c++17 -fsanitize=fuzzer fuzzer/b_plus_hash_map_fuzzer.cc -I.

Execute:

./a.out
./a.out -minimize_crash=1 -runs=10000 /tmp/tmp.b521097a4f49
./a.out /tmp/tmp.12345678/artifacts/minimized-from-185ecf42f208c2a7736a98ba0403f31868bcb681

To give an artifact path:

-artifact_prefix=/home/my-name/tmp/fuzz/artifacts/

Bazel

Fuzzing with bazel is possible but is currently disabled because it breaks bazel build ....

We would need to set clang/clang++ as compiler (gcc would not work anymore)
We would need to solve the problem that bazel build ... fails unless -fsanitize=fuzzer is set

Using a simple executable

Uncomment build rules in BUILD file, then: CC=clang bazel run //fuzzer:b_plus_multimap_fuzzer --config=fuzz

Using the bazel cc_fuzz_test
