[Frama-c-discuss] New Frama-C version: Fluorine



Thanks,

the patch file however tries to patch various files in src/wp/test that do
not exists (at least in the public release). Removing that solves the
problem and why works again with the following warnings:

File "/Users/xxxx/.frama-c-wp/typed/Axiomatic.why", line 16, characters
8-11: unused variable x_0
File
"/Users/xxxx/.frama-c-wp/project.session/../typed/strlen_Why3_ide.why",
line 22, characters 6-9: unused variable x_0
File

line 65, characters 6-9: unused variable x_1

curiously z3 is able to successfully prove everything in the original code
(without the addition of BASE and END)
