[Boost-users] [bind+signals] binding overloaded function + gcc4.6.2 = call of overloaded is ambiguous

Hi all, Such code can be built without problem using gcc3.4.3: typedef boost::signal< void () > Signal; Signal s; boost::bind( &Signal::operator(), &s ); but gcc4.6.2 returns: error: call of overloaded 'bind(<unresolved overloaded function type>, Signal*)' is ambiguous Is it expected behaviour? or problem in gcc4.6.2? Is there any solution except casting function pointer to particular type? Regards, Bogdan PS. I tried boost 1.38/1.48 and gcc 3.4.3/4.6.2
