8686,Not compilable with exceptions disabled,Norbert Riedlin <norbert.riedlin@…>,Christophe Henry,"With disabled exceptions the code in do_process_helper() won't compile under gcc (Used version was llvm-gcc-4.2 under MacOSX 10.7.5)
In the function template:
{{{
template <class StateType,class EventType>
HandledEnum do_process_helper(EventType const& evt, ::boost::mpl::false_ const &, bool is_direct_call)
try
{
    return this->do_process_event(evt,is_direct_call);
}
catch (std::exception& e)
{
    // give a chance to the concrete state machine to handle
    this->exception_caught(evt,*this,e);
}
//...
}
}}}

gcc will somehow forget about the formal parameter {{{e}}} in the catch clause but still insists on the code in the {{{catch}}} clause to be compilable. Apart from replacing {{{try}}} and {{{catch}}} by the boost macros {{{BOOST_TRY}}} etc. I also had to declare a local variable {{{std::exception e}}} that won't be used in any way apart from making the code compilable in the case without exceptions.
