Hey HJ, thanks for the feedback.

I am unable to reproduce this on x86_64 by using -m32. Can you paste in the
excess errors from libstdc++.log for just this test? Thanks.

Created attachment 22535
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=22535
invalid autoreduced testcase

Reproduced at x86_86-linux, r167127 and r167147. Attached is autoreduced
testcase - it is invalid, but maybe better than nothing. I don't have any
revision available that would accept the original source without crashing.

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());
}
