使用libfuzzer.a进行C ++模糊测试

问题描述

我使用libfuzzer.a编写我的第一个模糊测试代码， 这是我的代码

extern "C" int LLVMFuzzerTestOneInput(const uint8_t *Data,size_t Size) {

int size = Size;
printf("size=%d",Size);
return 0;  // Non-zero return values are reserved for future use.
}

但是当我运行这段代码时，我遇到了这个问题，怎么解决呢？

WARNING: Failed to find function "__sanitizer_acquire_crash_state".
