[Frama-c-discuss] Porting some simple example from Jessie to WP

For teaching, I am trying to port some examples I have to WP, the following
example could be proved by jessie, but it doesn't work with WP.

Can I have a hint ?

requires \valid(x)&&-10<*x<10;
requires \valid(y)&&-10<*y<10;
assigns *x;
assigns *y;
ensures *x == \old(*y);
ensures *y == \old(*x);

void echange(int *x, int *y)
