     Type:  Bugs              |      Status:  new           
Milestone:  To Be Determined  |   Component:  asio          
  Version:  Boost 1.47.0      |    Severity:  Problem

------------------------------+---------------------------------------------
 On the [http://lists.boost.org/boost-users/2011/07/69466.php mailinglist]
 it has been discovered, that including {{{boost/signals.hpp}}} before
 {{{boost/asio.hpp}}} causes a compile error in
 {{{asio/detail/impl/signal_set_service.ipp:74}}} saying ''"boost::signal":
 use of class template requires template argument list''.

 The following testcase has been used to confirm this under MSVC10:
 {{{
 #!c++
 #include <boost/signals.hpp>
 #include <boost/asio.hpp>

 int main(int argc, char **argv)
 {
     return 0;
 }
 }}}

 [http://lists.boost.org/boost-users/2011/07/69475.php Igor R] provided the
 following patch for
 {{{boost\asio\detail\impl\signal_set_service.ipp:71}}}:
 {{{
 #!diff
 - signal(signal_number, asio_signal_handler);
 + ::signal(signal_number, asio_signal_handler);
 }}}
