--- Comment #6 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
A bit more reduced:
% cat test_66214.ii
class A;
template <typename = int> class B {
typedef A value_type;
void m_fn1(const value_type &);
};
class A {
int m_upperBorder;
B<> m_tupelTypes;
};
% g++ -c -g test_66214.ii
test_66214.ii: In instantiation of ‘class B<>’:
test_66214.ii:8:7: required from here
test_66214.ii:2:33: error: TYPE_CANONICAL is not compatible
