[Frama-c-discuss] support assigns clauses

Hello,

thank you for your quick response.

I have the same results but when I remove the assigns-clause, everything
else will be solved.

Is there a connection between both VC?

I tried your examples and the assigns clauses are proved, at least by 
Simplify and Z3.

There is one unproved VC, but not related to assigns clause .
