Bug with templates

[Jim Foley]

    When I compile the source file below with g++ -c <filename.cc>
    I get an internal error:
bug.cc:40: Internal compiler error.
bug.cc:40: Please submit a full bug report to `egcs-bugs@cygnus.com'.

    This version of g++ is egcs-2.90.23 980102 (egcs-1.0.1 release), running on
    Linux version 2.0.30.


template <class td> class VEexpr;
template <class td> class VEbinaryExpr;


#define TYPEDEFS typedef typename td::Expr Expr;


class VEtypedef
{
public:
    typedef VEexpr<VEtypedef> Expr;
    typedef VEbinaryExpr<VEtypedef> BinaryExpr;
};

template <class td>
class VEexpr  : virtual public td
{
public:
    virtual void print() = 0;
};

template <class td>
class VEbinaryExpr : public td::Expr
{
    TYPEDEFS;

    Expr* _right;
    Expr* _left;

public:

    VEbinaryExpr(VEexpr<td>* right, VEexpr<td>* left)
    { _right = right; _left = left; }
    void print();
};

template VEbinaryExpr<VEtypedef>;
