3697,Lack of g++ symbol visibility support in boost::system,rbock@…,Beman Dawes,"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 

http://gcc.gnu.org/wiki/Visibility

Thank you for your time!

Roland
