Using lambda expression as Compare for std::set, when it's inside a vector

Question

I want to use a lambda expression as custom Compare for a std::set of integers. There are many answers on this site explaining how to do this, for example https://stackoverflow.com/a/46128321/10774939. And indeed,

#include <vector>
#include <set>
#include <iostream>

int main() {

    auto different_cmp = [](int i, int j) -> bool {
        return j < i;
    };

    std::set<int, decltype(different_cmp)> integers(different_cmp);

    integers.insert(3);
    integers.insert(4);
    integers.insert(1);
    for (int integer : integers) {
        std::cout << integer << " ";
    }

    return 0;
}

compiles and outputs

4 3 1

as expected. However, when I try to put this set in a vector with

    std::vector<std::set<int, decltype(different_cmp)>> vec_of_integers;
    vec_of_integers.push_back(integers);

the compiler complains. I'm using Visual Studio 2017 and I get different compiler errors depending on the surrounding code. In the above example, it's

1>c:\program files (x86)\microsoft visual studio\2017\community\vc\tools\msvc\14.16.27023\include\utility(77): error C2664: 'void std::swap(std::exception_ptr &,std::exception_ptr &) noexcept': cannot convert argument 1 from '_Ty' to 'std::exception_ptr &'
1>        with
1>        [
1>            _Ty=main::<lambda_48847b4f831139ed92f5310c6e06eea1>
1>        ]

Most of the errors I've seen so far with this seem to have to do with copying the set.

So my question is:

Why does the above code not work and how can I make it work, while still using a locally defined lambda?

Answer 1

This seems to be a bug in MS compiler as it compiles well with GCC and Clang.

To make it work in MS Compiler (Visual Studio 2017) you can do this:

std::vector<std::set<int, decltype(different_cmp)>> vec_of_integers{integers};

This compiles cleanly. See here.
