I ran into this issue when I compiled with a newer version of g++. For 
me the only place where there was an issue was in 
FrameValues::validate(). The iteration in that code is a bit strange and 
by re-writing it a bit you could make sure that the prev value was 
always initialized.

I think your fix is probably better and simpler. So, for me your change 
looks good. I just wanted to mention the other solution in case you'd 
prefer it.

Consider your patch reviewed by me if you want to push it urgently.

Thanks,
Bengt
