You can demangle the symbol like this:

$ c++filt _ZNSs4_Rep20_S_empty_rep_storageE
std::basic_string<char, std::char_traits<char>, std::allocator<char> >::_Rep::_S_empty_rep_storage

So it has to do with the std::string include I tried for SWIG. I've
removed it now, it's not used right now. So now it shouldn't reference
it.

Yes, that's a good idea.
