 Similar to #2309 (class symbols) and #3347 (method sybols):

 If you compile a library which throws boost::system::system_error with

 g++ -fvisibility=hidden

 the exception cannot be caught as system_error (but as runtime_error).

 Using


 {{{
 #pragma GCC visibility push(default)
 #include <boost/system/system_error.hpp>
 #pragma GCC visibility pop

 }}}

 in the library code helps, but it requires a lot of attention.

 It would be really, really cool if all boost libraries would add
 visibility to the public classes, see also

 Thank you for your time!
