>From https://stackoverflow.com/questions/69696170:
variant#L568:
template<typename _Tp, typename _Up>
_GLIBCXX20_CONSTEXPR
void
__variant_construct_single(_Tp&& __lhs, _Up&& __rhs_mem)
{
using _Type = __remove_cvref_t<_Up>;
This should be using _Type = remove_reference_t<_Up>.
#include <string>
#include <variant>
int main() {
using var_t = std::variant<const int, const std::string>;
var_t v;
var_t v2(v);
}
