fix submitted.

@jbo_85: earlier today I started to work on the OAM and I had the boundary checks locally implemented. but I had given up with optimized build, so I was unaware that it was the required fix.

I hope this fixes all the problems previously experienced. once again, thanks a lot for the tip!!

@judge: is Superscope support compiling now? I'd like to leave the proper checks there even if we currently only scan positive coordinates...
