no match for ..., internal compiler error

[Loring Holden <lsh at cs dot brown dot edu>]

I got what I think is a g++ compiler error, building g++ from the CVS sources
as of 11:23 pm EDT on Jul 28, 1999.  I also got an internal compiler error I
think is related.

Version:
GNU C++ version 2.96 19990728 (experimental) on sparc-sun-solaris2.7

Options:
% g++ g++conditional2.C
g++conditional2.C: In function `void problem_function()':
g++conditional2.C:13: no match for `bool ? const Wtransf (&)() : Wtransf'

% g++ g++conditional3.C
g++conditional3.C: In method `class Wvec hashvar<Wvec>::get() const':
g++conditional3.C:27:   instantiated from here
g++conditional3.C:21: Internal compiler error in `emit_move_insn', at expr.c:2565
Please submit a full bug report.
See <URL:http://egcs.cygnus.com/faq.html#bugreport> for instructions.

Thanks,
Loring
PS-
The source to g++conditional2.C:

class Wtransf {};

const Wtransf Identity2() = Wtransf();
class HELPER {
   public:
      int  current() const  { return 0; }
};

void
problem_function()
{
   HELPER tm;
   Wtransf delta  = (tm.current()) ? Identity2 : Wtransf();
}



The source to g++conditional3.C:
template <class V>
class _vec3d
{
   public:
      double _x, _y;
};

class Wvec : public _vec3d<int> { };

template <class T>
class TDI {
   public:
      T   &get();
};

template <class T>
class hashvar {
  public :
   T       _val;
   TDI<T> *val() const;
   T       get() const { return true ? val()->get() : _val; }
};

int
main() {
   hashvar<Wvec>  CONSTRAINT_DIR;
   CONSTRAINT_DIR.get();
}
