I get the same ICE (same line number 5490) with:

template<class _T1, class _T2> struct pair {
        _T2 second;
        template<class _U1, class _U2> constexpr pair(const pair<_U1, _U2>&
__p) : second(__p.second) { }
};
pair<int,int> make_pair();
struct Gmpfr{
        Gmpfr(int);
};
struct Gmpfi{
        Gmpfi(pair<const Gmpfr,const Gmpfr> bounds){ }
};
template <class CT> void test_interval_io(CT x){
        Gmpfi a(x);
}
int main(){
        test_interval_io<pair<int,Gmpfr> > (make_pair());
}
