我不希望解决方案更改源代码。请让Clang分析源代码而不进行修改。

• • 测试类. cpp**

#include <Windows.h>

class TestClass {
public:
    TestClass(LPTSTR test);
};

TestClass::TestClass(LPTSTR i_dumpPath) {
    BSTR bstr = SysAllocString(i_dumpPath);
}

• • 运行命令**

clang TestClass.cpp -m32 -w

• • 产出**

TestClass.cpp:9:17: error: no matching function for call to 'SysAllocString'
    BSTR bstr = SysAllocString(i_dumpPath);
                ^~~~~~~~~~~~~~
