[Frama-c-discuss] wp <==> problem

Hi,

i find a problem with the wp plugin in Frama-C, whose version is "Frama-C
Carbon-20110201+dev".
I start Frama-C with the following command:  "frama-c-gui -wp  -wp-proof
alt-ergo binary_search2.c &".

In the file "binary_search2.c",  Frama-c can prove line 46,47,49, but line
51.
If line 46,46,49 can be proved, line 51 should be proved.
Because if
1:a<==>b
2:b<==>c
3:(a<==>b && b<==>c) ==> (a<==>c)
is true, then
4: a<==>c
should also be true.
