[Boost-users] [boost signal] problem with borland c++ builder 6

Hi

I'm trying to use boost::signal to replace a library of my own
It compiles well but at runtime It raises an exception on the following line

        boost::signal<> sig;

the exception is raised in

function_template.hpp
       template<
         typename FunctionObj,
         typename R BOOST_FUNCTION_COMMA
         BOOST_FUNCTION_TEMPLATE_PARMS
       >
       struct BOOST_FUNCTION_FUNCTION_OBJ_INVOKER
       {
         static R invoke(function_buffer& function_obj_ptr 
BOOST_FUNCTION_COMMA
                         BOOST_FUNCTION_PARMS)

         {
           FunctionObj* f;
           if 
(function_allows_small_object_optimization<FunctionObj>::value)
             f = reinterpret_cast<FunctionObj*>(&function_obj_ptr.data);
           else
             f = reinterpret_cast<FunctionObj*>(function_obj_ptr.obj_ptr);

           return (*f)(BOOST_FUNCTION_ARGS);  <<<<< exception raised here

         }
       };

Does the sig have to be initialized in a specific way ???
