Unfortunately your patch is triggering a bug somewhere which breaks  
176.gcc. Dan is trying to track it down but it's illusive. We don't  
know what part of your patch is causing this so it's best not to check  
anything in. I'm sure we'll eventually figure out the issue. Thanks  
for your patience.
