That has nothing to do with "wasting" bits as you stated before. This is a totally new issue, and can easily be solved by setting a limit peak bitrate, just like the old mpeg-2 encoders had for dvd video not superpassing 9800kb/s or so.
You can have your peak limit set, and still work with a higher --qcomp. This is no issue at all. I am no expert on x264, so I am not sure if you can set your peak bitrate at current state. Some dev please help with this.
