[Bug c++/15227] New: [3.3/3.4/3.5 regression] Trouble with invalid function definition

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following testcase (which is invalid, as A::B doesn't exist)
causes trouble:

=============================================
template<typename> struct A {};

template<typename T> void A<T>::B::foo() {}
=============================================

GCC 2.95.3 correctly rejects the code,
gcc 3.1 - 3.3.4 wrongly accept it,
gcc 3.0.x, 3.4.0 and mainline segfault.
