Attached the source file. The lines above the error causing code (ln. 66 and
ln. 72) are accepted by the compiler.

Comment 4 Jakub Jelinek 2005-02-07 21:45:20 UTC
Simplified testcase:

extern double foo (double);

template <class T>
struct A
{
  T y () const;
};

typedef A <float> B;

template <unsigned int T>
struct C
{
  C ();
  B c;
  float r;
};

template <unsigned int T>
C<T>::C ()
{
  r = foo (c.y);
}

G++ 3.4 ICEs on this, G++ 3.2 accepts it, G++ CVS HEAD rejects it with:
147385.ii: In constructor <T>::C()':
147385.ii:22: error: not enough type information


Comment 5 Jakub Jelinek 2005-02-07 21:58:40 UTC
Given that this is ICE on invalid as far as I can judge (you want
cartesian.y () instead of cartesian.y and similarly for x and z), I'm moving this
upstream.
