Question

在调试模式下的MSVC 15.8.5上，我明白了

运行时检查失败＃2-围绕变量'insert_into'进行堆栈已损坏。

MSVC中是否存在错误或我做错了什么？

在clang版本6.0.0-1ubuntu2和clang版本7.0.0-svn341916-1〜exp1〜20180911115939.26上运行良好

#include <set>

template <typename... T>
struct Overload : T...
{
//support struct for combining and overloading multiple lambdas
    using T::operator()...;
};
template <typename... T>
Overload(T...)->Overload<T...>;

using BuiltSet = std::set<std::string>;

template <typename... Args>
BuiltSet MakeBuildSet(const Args&... args)
{
//takes a list of arguments if an argument is a 
// BuiltSet each element is added to headers, 
// otherwise the arg itself is added to headers
    BuiltSet headers{};

//Construct a lambda with overloading on if argument is a BuiltSet or not
    const Overload insert_into{
        [](const BuiltSet& h, BuiltSet& headers) {
            headers.insert(h.begin(), h.end());
        },
        [](const auto& arg, BuiltSet& headers) { 
            headers.insert(arg); 
        }
    };
//Fold over arguments applying the lambda on each element
    (insert_into(args, headers), ...);
    return headers;
}

int main(int argc, char** argv)
{
    MakeBuildSet(MakeBuildSet("a", "b", "c"), "a", "b", "c");
    return 0;
}

Answer 1

MSVC bug，所以这是编译器中的缺陷。

变量'...'周围的堆栈已损坏
