Similarily:

throw std::runtime_error("my error");

What happens if std::runtime_error's constructor throws? (a temporary
std::string is created so the dynamic allocation could cause std::bad_alloc
to be thrown)

Apparently people consider this a non-issue.  And so, it seems the fact that
boost::wrap_string could throw is also a non-issue.
