Subject: [Boost-users] [exception] Passing existing exception hierarchies between threads

Hi,
I am trying to pass Poco::Exeption from worker thread to a client
thread/future. Idea is simple:
try
{
operationThatMyThrowPocoException();
}
catch (const Poco::Exception& e)
{
// rethrow with exception_ptr support so can be passed between threads
BOOST_THROW_EXCEPTION(e);
}
but this causes compilation error because Poco::Exception defines
clone() method on its own:
error C2555: 'boost::exception_detail::clone_impl<T>::clone':
overriding virtual function return type differs and is not covariant
from 'Poco::Exception::clone' c:\devel\boost_1_50_0\boost\exception\exception.hpp 468
Is there a way to use BOOST_THROW_EXCEPTION /
enable_current_exception() with existing exception hierarchies that
define clone() already?
Regards,
Szymon
