Comment (by vivien.millet@…):

 To be more precise it's when we derive from a class which have its copy
 constructor private (it might be a known case)

 {{{

 class NoCopy
 {
 private:
     NoCopy(const NoCopy&);
 };

 class DerivedNoCopy : public NoCopy
 {

 };

 static const int ok = !boost::is_copy_constructible<NoCopy>::value; // OK

 static const int error =
 !boost::is_copy_constructible<DerivedNoCopy>::value; // error C2248:
 'NoCopy::NoCopy'Â : cannot access private member declared in class 'NoCopy'

 }}}
