Boost::signal compil error under Visual studio 6

Hello, I've got a problem using the signal library, receiving this compiler error: F:\LIBSPC\BOOST\boost/iterator_adaptors.hpp(872) : fatal error C1001: INTERNAL COMPILER ERROR (compiler file 'msc1.cpp', line 1794) Please choose the Technical Support command on the Visual C++ Help menu, or open the Technical Support help file for more information F:\LIBSPC\BOOST\boost/signals/signal_template.hpp(303) : see reference to class template instantiation 'boost::iterator_adaptor,struct _STL::_Nonconst_traits > >,class boost::signals::detail::slot_call_policies >,struct _STL::_Rb_tree_iterator,struct _STL::_Nonconst_traits > >

,bool,bool &,bool *,struct _STL::input_iterator_tag,struct boost::detail::default_argument>' being compiled

I'm just sending a signal at this line, as follow: // i_x and i_y are ints MouseSignalLClick(i_x, i_y); MouseSignalLClick is member of a class, defined as follow: boost::signal2 MouseSignalLClick; I'm using Boost library version 1.30, and visual sp5. Thanks.
