Hello group, Boost.Function is exhibiting differing behavior in different boost releases: //-------------------------- struct F { void operator()() { } }; F obj; // assume obj remains in scope for duration of sample boost::function<void()> f1 = boost::ref( obj ); boost::function<void()> f2 = f1; assert( f1 == boost::ref( obj ) ); assert( f2 == boost::ref( obj ) ); // Passes in 1.35.0, Fails in 1.39.0 boost::function<void()> f3 = boost::ref( obj ); boost::function<void()> f4; f3.swap( f4 ); assert( f3 != boost::ref( obj ) ); assert( f4 == boost::ref( obj ) ); // Passes in 1.35.0, Fails in 1.39.0 //--------------------------- I'm assuming 1.35.0 is demonstrating the correct behavior whereas 1.39.0 is exhibiting a bug, but I thought I'd defer to the group before I reported it. Am I correct?
