Since PR 16929 got a little confusing, I'm opening a new PR for the
following problem:
Since gcc 3.4.0 we accept the following invalid code snippet. The invalid
default parameter "a" is not even diagnosed at instantiation time.
(This is different from PT 17011 - also a spin-off from PR16929 -
which is just a QoI issue.)
===========================================
template<typename> struct A {};
template<typename T> struct B
{
A<T> a;
void foo(A<T> = a);
};
template struct B<int>;
===========================================
With 3.3.5 and before we got a decent error message:
bug.cc:7: error: invalid use of member `B<T>::a'
