Hi,
I noticed that both in 2.6.1 and current trunk (cabc88f) the move
constructor for the slot is not selected by the compiler (gcc 4.9 and 4.8.4
tried) even in the most trivial case. Take test_slot_move.cc unit test for
example:
sigc::slot<void,int> s2(std::move(s1));
If you now do (bool)s1 it will evaluate to 'true'. Also s1() works and calls
foo() as if s1 wasn't moved to s2. I tried to add traces to slot1 copy and move
constructors and indeed only copy constructor is called, but not move. So,
something is wrong here - either compiler bug (unlikely) or some code in the
slot/slot_base/functor_base prevents compiler from selecting move semantics for
constructor.
BR, Andrey
