c++ - Intel Inspector XE 2012 警告 #12367 - 传递给 vector::erase() 的迭代器参数切片

Question

运行 Build | 时收到警告 #12367为英特尔静态分析构建解决方案，但我看不到我的代码有问题。有人有想法吗？

warning #12367: slicing of object passed as actual argument 2 in call "std::_Vector_iterator > > std::vector >::erase(std::_Vector_const_iterator > >)" occurs due to implicit type conversion

 pragma warning(suppress: 4995)
    #include <vector>

    class __declspec(dllexport) MxPluginLib //nothing special here, not derived class etc
    {
    public:
      // ...
    private:
     //  ... nothing special here

    };


    class __declspec(dllexport) MxPluginManager 
    {
    public:
       //...
    private:
    #pragma warning(suppress: 4251)
        std::vector<MxPluginLib *> _Libs;

    };

    bool MxPluginManager::DeleteNextUnselected()
    {
        bool erased = false;
        size_t cnt = _Libs.size();
        if (cnt > 0 )
        {
            for (size_t x = 0; x < cnt; x++)
            {
                if (_Libs[x]->GetSelection() == false)
                {
                    delete  _Libs[x];
                    _Libs[x] = '\0';
                    _Libs.erase(_Libs.begin()+x);  //THIS IS WHERE THE WARNING IS GENERATED
                    erased = true;
                    break;
                }
            }
        }
        return erased;
    }

Answer 1

在我看来唯一奇怪的是

_Libs[x] = '\0';

这可能会让分析器认为您存储的是字符而不是指针。由于无论如何您都在删除该元素，因此您实际上并不需要它 - 将其删除，看看它是否能解决您的问题。
