Looks like you are attemping to bind a temporary to a non-const reference. This
is invalid. More to the point, a copy constructor should always be declared as
A(A const &), not A(A&). BasicList<T>'s copy constructor seems to violate this.

BTW, when upgrading to 3.4, http://gcc.gnu.org/gcc-3.4/changes.html can be very
helpful.
