    Concept/utACK fad058a

    Annoyingly, this doesn't work out of the box on macOS:

    checking whether C++ compiler accepts -Werror... yes
checking whether C++ compiler accepts -fsanitize=fuzzer,address... yes
checking whether the linker accepts -fsanitize=fuzzer,address... no
configure: error: linker did not accept requested flags, you are missing required libraries

    Seemingly because Xcode 10 doesn't include a copy of libclang_rt.fuzzer_osx.a. i.e:

    clang++ -fsanitize=fuzzer -o fuzzme fuzzme.cpp
ld: file not found: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/10.0.0/lib/darwin/libclang_rt.fuzzer_osx.a
clang: error: linker command failed with exit code 1 (use -v to see invocation)

    Configuring Core with all other sanitizers, address, thread, undefined etc, works correctly.

    Will test in a Linux env shortly.
