I think there may be two issues here demonstrated in the code below. The
example code is distilled from ./include/c++/4.3.0/tr1_imp/hashtable. GCC
compiles this code without a diagnostic, but both the Intel and Microsoft
compilers diagnose an error with too few template args for __detail::_Map_base'
:
% cl -c t.cpp -nologo
t.cpp
t.cpp(10) : error C2976: '__detail::_Map_base' : too few template arguments
t.cpp(4) : see declaration of '__detail::_Map_base'
% cat t.cpp
namespace __detail
{
template<typename _Key, typename _Value, typename _Ex, bool __unique,
typename _Hashtable> struct _Map_base { };
}
struct _Hashtable
{
template<typename _Key2, typename _Pair, typename _Hashtable>
friend struct __detail::_Map_base;
};
So, you may want to fix the template in <tr1_imp/hashtable> and/or try to
diagnose this case in the compilation.
