# Running the fuzzers locally
There is a [helper script](build.sh) to build the fuzzers, which has only been
tested on Debian and Ubuntu linux so far. There should be no problems fuzzing on
Windows (using clang>=8) or on Mac, but the script will probably not work out of
the box.
Something along
```sh
mkdir build
cd build
export CXX=clang++
export CXXFLAGS="-fsanitize=fuzzer-no-link -DFUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION= -g"
cmake .. -DFMT_SAFE_DURATION_CAST=On -DFMT_FUZZ=On -DFMT_FUZZ_LINKMAIN=Off -DFMT_FUZZ_LDFLAGS="-fsanitize=fuzzer"
cmake --build .
```
should work to build the fuzzers for all platforms which clang supports.
Execute a fuzzer with for instance
```sh
cd build
export UBSAN_OPTIONS=halt_on_error=1
mkdir out_chrono
bin/fuzzer_chrono_duration out_chrono
```

// A set of macros for testing Google Test assertions or code that's expected
// to generate Google Test fatal failures. It verifies that the given
// statement will cause exactly one fatal Google Test failure with 'substr'
// being part of the failure message.
//
// There are two different versions of this macro. EXPECT_FATAL_FAILURE only
// affects and considers failures generated in the current thread and
// EXPECT_FATAL_FAILURE_ON_ALL_THREADS does the same but for all threads.
//
// The verification of the assertion is done correctly even when the statement
// throws an exception or aborts the current function.
//
// Known restrictions:
// - 'statement' cannot reference local non-static variables or
// non-static members of the current object.
// - 'statement' cannot return a value.
// - You cannot stream a failure message to this macro.
//
// Note that even though the implementations of the following two
// macros are much alike, we cannot refactor them to use a common
// helper macro, due to some peculiarity in how the preprocessor
// works. The AcceptsMacroThatExpandsToUnprotectedComma test in
// gtest_unittest.cc will fail to compile if we do that.
