Well, if the DEBUG code never changed any behaviors at all, it would be pretty useless, wouldn't it? In this case, the change in behavior involves printing out a kernel message announcing a bug. Causing the submission to fail also helps draw people's attention to the bug. Under the circumstances, I think this is understandable and not truly broken.
