Test case for the compiler issue

Ok, I've isolated the problem into a simpler test case. I'm not so sure this is a gcc issue, since the test case also fails here with clang, I don't understand why WebKit worked when built with clang, though. The problem seems to be that we are using the parent class, casting to the derived class, and using a lambda function (if the print method in the test case, calls a member function it works too). I'm not a C++11 expert, but the fact that when using the derived class directly, the build fails when calling print without using std::move for the arguments, makes me thing whether we should actually passing WTF::move for all the arguments passed to AsyncRequest::completeRequest(). I wonder if by using the parent class method and casting we are confusing the compiler that should fail like when using the derived class directly, but it doesn't.
