Surely we can workaround > it in boost by doing the 1.61 transition at the same time, but what about other > libraries? I get the impression virtual functions are handled differently. For example, in htmlcxx (https://bugs.debian.org/811964), virtual destructors used to result in symbols attached to the declaring class (HTML::Exception::~Exception()), but with GCC 6 they result in symbols attached to the concrete classes (Uri::Exception::~Exception()).
