So the problem seems to be related to -fstandalone-debug (at least one part of it). Right now there is a problem, where -fstandalone-debug and libstdc++-dbg cannot coexists for whatever reason: -fstandalone-debug, libstdc++-dbg uninstalled -> test works fine -fno-standalone-debug, libstdc++-dbg installed -> test works fine -fno-standalone-debug, libstdc++-dbg uninstalled -> failure, cannot find std::string definition [as expected] -fstandalone-debug, libstdc++-dbg installed -> failure, for whatever reason we end up calling std::random_device::_M_init() instead of std::string::c_str() [bad]
