--- Comment #2 from Sandro Mani <manisandro at gmail dot com> ---
Minimum reproducer seems to be:


// repro.cpp
#include <string>
#include <vector>
#include <utility>

struct S
{
    std::string s;
};

int main()
{
    std::vector<S> v;

    S x = {};
    x.s = "hello";

    v.push_back(std::move(x));
}
