Description :
Running "frama-c -wp ilog2_beh.c -wp-prop ilog2 -wp-prover alt-ergo -wp-prover cvc4" on the attached program proves everything except (the lemmas and) loop invariant "a".
However, when lines 16,27,30,36,41 are uncommented, i.e. the default behavior is assigned an explicit name, everything except (the lemmas and) the loop variant is proven instead.
Naming vs. not naming a behavior shouldn't have such an influence.
