Milestone:  To Be Determined          |   Component:  exception     
  Version:  Boost 1.44.0              |    Severity:  Problem

 The following lines (line 139/140) in
 boost/exception/diagnostic_information.hpp gives a syntax error when
 trying to instrument code that includes the file using TestCocoon 1.4.0
 with Visual C++ 9.0:
 {{{
 tmp << std::string("Dynamic exception type: ") <<
 units::detail::demangle((be?BOOST_EXCEPTION_DYNAMIC_TYPEID(*be):BOOST_EXCEPTION_DYNAMIC_TYPEID(*se)).type_.name())
 << '\n';
 }}}

 Since BOOST_EXCEPTION_DYNAMIC_TYPEID is a macro that evaluates to ::...,
 the resulting ::: causes a syntax error (it appears to be fine when using
 plain Visual C++ 9.0). In any case, it would be safer to either change the
 macro or this use of it to by adding parentheses:

 {{{
 tmp << std::string("Dynamic exception type: ") <<
 units::detail::demangle((be?(BOOST_EXCEPTION_DYNAMIC_TYPEID(*be)):(BOOST_EXCEPTION_DYNAMIC_TYPEID(*se))).type_.name())
 << '\n';
 }}}
