           Summary: Default arguments do not work in template template
                    functions
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org

The following code does not compile in clang, because there is only one
parameter on IntervalMap in the typedef, instead of two. It does compile in g++
and comeau.


template<class _T, class Traits> class IM;

template <class T, class Trt, template<class _T, class Traits = int> class
IntervalMap>
void foo(IntervalMap<T,Trt>* m)
{ typedef IntervalMap<int> type; }
Hm
void f(IM<int, int>* m)
{ foo(m); }
