Platform - OS - OS Version -
Product Version Frama-C Neon-20140301 Target Version - Fixed in Version -

Description :

In a program similar to the enclosed example, the e1_wp property was proved by a previous version of WP, but is not proved anymore with Neon. Adding the commented loop invariant doesn't help. I tried to simplify as much as I can, but I don't understand what is going wrong in the proof obligation.

Steps To Reproduce :

$ frama-c -wp-prop a1_val bts1940.c
