      The following piece of code causes a crash, and valgrind reports invalid read in QFutureInterfaceBase::isChainCanceled().
       

      	vector<QFuture<int>> futures {
		QtFuture::makeReadyFuture<int>(0).then([](int i) { return i;})
	};

	QtFuture::whenAll(futures.begin(), futures.end()).then([](const QList<QFuture<int>>& fl) {
	});
