The name in the error message:
  B<template <class> class C>::C<int>::C(void)
suggests the compiler is not generating accurate names from the
template instantiations.  The above name should be either:

    B2::C<int>::C(void)
  = B<B1::C>::C<int>::C(void)
  = B<B<B<A>::C>::C>::C<int>::C(void)

    B3::C<int>::C(void)
  = B<B2::C>::C<int>::C(void)
  = B<B<B<B<A>::C>::C>::C>::C<int>::C(void)
