Description

Building in the RelWithDebInfo or Release configurations on FreeBSD fails to build executables that use the C++ binding with a link error which is effectively this demangled symbol not found:

std::ostream& operator<<(std::ostream&, std::string)

[But it's much longer in real life because it's massively templated]
