I can't quite decide if this sounds great or awful. If code hasn't been adequately verified and/or tested, helping someone address those omissions (which would require fixing the bugs they make manifest) would be great. OTOH, merely "pointing out" or saying "this doesn't work" sounds not so great, and "similar to the one I had in mind" rings a huge NIH alarm bell. Instead of wondering whether you were being a prick, I'd highly recommend asking your other peers for suggestions on making the process less adversarial.
