Comment (by Jonathan Jones <jonathan.jones@…>):

 It's not enough to ensure that boost::exception,
 boost::exception_detail::clone_base, and boost::unknown_exception have
 default symbol visibility on GCC.  It appears that boost::error_info also
 needs to be decorated with default visibility.  Otherwise, calls to
 get_error_info on exceptions propagated across library boundaries will
 always return NULL, rendering boost::exception essentially useless.
