For what it's worth, that trick is not very portable in practice, at
least not to many of the older compilers that Boost.Bind is trying to
support.  I suggest that instead, you do something like this:

void ExceptionFilter(boost::function0<> f)
{
     try {
         f();
     } catch(Exception1 const& e) {
         //Blah-blah 1
     } catch(Exception2 const& e) {
         //Blah-blah 2
     } catch(Exception3 const& e) {
         //Blah-blah 3
     } catch(Exception4 const& e) {
         //Blah-blah 4
     } catch(Exception5 const& e) {
         throw; //Just rethrow
     } catch(...) {
         //Something other
     }
}
