Comment (by Dimitrij Drus):

 I just moved to the 1.46.1 version of boost. It still lacks the visibility
 support for boost::exception. The trunk has corresponding adjustments,
 which however are not complete. Within the exception.hpp there is a
 forward declaration of the exception class. Without surrounding this
 forward declaration with GCC visibility pragmas too, the boost::exception
 can't be catched if throwed across the shared lib boundaries.

 The behaviour was observed on Ubuntu 10.04 with gcc version 4.4.3.
