Reduced testcase:
template<class _CharT> struct char_traits {};
template<typename _CharT, typename _Traits = char_traits<_CharT> >
class basic_ostream {};
template<class _Traits>
basic_ostream<char, _Traits>&
operator<<(basic_ostream<char, _Traits>& __out, const char* __s);
extern basic_ostream<char> cout;
template<template<int> class CT, int TA>
void operator<<(CT<TA>, int);
int main()
{
cout << "Hello, world\n";
