As I understand it, there are some implicit default constructors that are
normally present --- but if you declare certain (any?) constructors of your
own, the default constructors are not generated. If you don't explicitly
create those constructors yourself and then do something that uses the
constructor (often a copy constructor used implicitly), you get that
somewhat peculiar error from clang. g++ reports it differently (IIRC just
as a missing constructor, which is confusing in a different way if you're
not aware of when C++ implicitly creates some constructors).

(I have not worked with C++ in a long time, but Stack Overflow seems to
have a lot of people asking about this error.)
