It should be ignored by SWIG, but looks like it's not...
I don't think that's the problem.
In C++98 constructing std::vector<X> v(1); would invoke X's default
constructor in the caller's context, so if the default constructor is
private then the caller must be a member or friend of X.
In C++11 the default constructor will be invoked deep inside
std::vector, or one of its helper functions.
The code is basically invalid in C++11. It should either make the
default constructor public (the simplest fix), or change how the
vector is constructed (which seems to come from Swig, so might be
difficult).
