           Summary: typedef to nested template causes error
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: benko at sztaki dot hu
                CC: gcc-bugs at gcc dot gnu dot org
  GCC host triplet: i686-pc-linux-gnu

If this is an error at all, it's a regression from 3.3.
If struct a below is non-template, then it compiles through.

arta:~/c/proba$ cat templ_typedef.cc
template <typename T>
struct a
{
  template <typename U>
  struct i
  {};
};

template <typename T, typename U>
struct b
{
  typedef typename a<T>::i<U> a_t; // line 12
};
