[Frama-c-discuss] WP - Verifiable annotations with some types but not others

Sorry about that but I did a mistake on my last message.
The correct clause was:

requires \forall unsigned char n; 0 <= n < 2 ==> \valid_range(&b.val[n],0,1);
or
requires \forall unsigned char n; 0 <= n < 2 ==> \valid(&b.val[n]+(0..1));

This still does the trick but I can't prove it.
