Comment (by Dimitrij Drus <dadrus@…>):

 Yes. Catching boost::exception thrown over the shared library boundaries
 is only possible after surrounding the forward declaration with the
 visibility pragmas. Patch is attached.

 One can use the test attached by Jonathan to verify this. Jonathan,
 however, expects the class boost::exception_detail::clone_base be exported
 (surrounded with gcc visibility pragmas) too, that's why corresponding
 test cases fail.

 Dimitrij
