It's a name conflict.  They happen.  I'd have trouble if I wanted to 
have a sizeof member in my struct too.  If you want to be sure to get 
the struct's member then use p[0].value.

'Value' is too common, though.  If you were going to go that route it 
should definitely be something like .iterVal or some other word less 
likely to conflict.

I'm not saying it's the right way to go, just that it could be made to 
work if needed.
