[Frama-c-discuss] problem about initial values for pointer type

You are talking about the initial values of the entry point's
arguments (and of global variables if using option -lib-entry) in the
value analysis.

You need to use -lib-entry if you want globals to be treated like
this. Also, the shape of initial values that you describe is only
exactly as you describe in the Frama-C Carbon version. In earlier
versions, arrays were treated uniformly, with no difference between
the first few cells and the remaining ones.
