clang++ using -stdlib=libc++ defines const_reference as a class, to map boolean vectors onto a bit set. Because swig does not "see" the type as "const &" it generates incorrect code for this case, generating a declaration like: const_reference result; When const_reference is a typedef to 'bool' as is the case with stdlibc++ this works. When this is actually a constant reference, this is clearly invalid since it is not initialized. For libc++, this is a class which cannot be default constructed, resulting in an error. The fix is to explicitly define the various accessor extensions as having a bool return type for this specialization.
