[class.ctor] p6
A default constructor that is defaulted and not defined as deleted is
implicitly defined when it is odr-used (3.2) to create an object of its
class type (1.8) or when it is explicitly defaulted after its first
declaration. The implicitly-defined default constructor performs the
set of initializations of the class that would be
performed by a user-written default constructor for that class with no
ctor-initializer (12.6.2) and an empty compound-statement.
