[Frama-c-discuss] Floating point computations with WP and Jessie

For Jessie, I just discovered that I can prove all VCs with Alt-Ergo +
CVC3 if I use
frama-c -jessie  r_ges.c
but not if I use
frama-c -jessie -jessie-atp=gui.
The latter fails with Alt-Ergo, CVC3, Simplify, Z3.

I use Frama-C Nitrogen + Jessie 2.30 + Why3 0.72. 

WP with any of the above provers fails to verify the call precondition
for r_ges = r_seq(r1,tmp). I haven't tried the latest WP plugin though.
