--- Comment #1 from Daniel Krügler <daniel.kruegler at googlemail dot com> 2013-04-09 09:10:52 UTC ---
There are several problems in your example:

1) You have not declared a default constructor in template Stack, but you have
provided user-declared constructors (The deleted ones). This has the effect
that the Stack template has a no implicitly declared default constructor, which
again has the effect that the initializer-list constructor generated by the
compiler in vector_stack is deleted, because it would implicitly call the
missing default constructor of Stack. Solution: Add a (defaulted) default
constructor to the Stack template.

2) The clone function in vector_stack would call the copy constructor of that
type. But this one is deleted, because the Stack template has an explicitly
deleted copy constructor. This is a design error.
