cpp_class_definition.i:5: Error: 'Space1::A' resolves to 'Space1::A' and
was incorrectly instantiated in scope 'Space2' instead of within scope 'Space1'.
Previously some symbols would have been instantiated in the wrong scope and led
to lots of scope problems involving SWIG typemaps, features, renames etc.
You will need to correct the scope used in other SWIG directives which do not
support 'using declarations' and 'using directives'. For example, if you previously had:
%rename(Zap) vector<int>::clear;
using namespace std;
%template(VectorInt) vector<int>;
Prior versions of SWIG incorrectly instantiated vector<int> in the global namespace
and so the %rename matched. Now the template is instantiated in the correct namespace,
so is fully qualified as std::vector<int>. The other SWIG directives need correcting as
they do not follow 'using declarations' and 'using directives'. Change it to:
%rename(Zap) std::vector<int>::clear;
using namespace std;
%template(vin) vector<int>;
