Clang 8发行说明中有以下内容：

• 允许在MinGW上使用Address Sanitizer和Undefined Behavior Sanitizer。

但是，我无法弄清楚如何正确使用它们。

我将Clang 8.0.0与MSYS2 MinGW GCC结合使用。确切的细节在问题的底部。

我正在尝试编译以下最少的代码：

1.cpp

#include <iostream>

int main()
{
    // Testing ubsan
    int x = 0x7fffffff;
    x++;
    std::cout << x << std::endl;

    // Testing asan
    int *y = new int;
    delete y;
    std::cout << *y << std::endl;
}

以下是结果-fsanitize=address：

# /z/Lander/LLVM/bin/clang++ -target x86_64-w64-windows-gnu -fsanitize=address 1.cpp
