Lunderberg c7fcde7c76 Fixed compilation error when binding function accepting some forms of std::function (#689) ... * Fixed compilation error when defining function accepting some forms of std::function. The compilation error happens only when the functional.h header is present, and the build is done in debug mode, with NDEBUG being undefined. In addition, the std::function must accept an abstract base class by reference. The compilation error occurred in cast.h, when trying to construct a std::tuple<AbstractBase>, rather than a std::tuple<AbstractBase&>. This was caused by functional.h using std::move rather than std::forward, changing the signature of the function being used. This commit contains the fix, along with a test that exhibits the issue when compiled in debug mode without the fix applied. * Moved new std::function tests into test_callbacks, added callback_with_movable test.		2017-02-22 20:00:59 +01:00
