Since you implement a visitor by copy which returns a new project, you 
should use option -then-on on this new project. However, calling the 
function "prepare_jessie" before computing the initial AST is still 
required in order to not fall into your previous crash.

Roughly speaking, the option -then-on is the command line counterpart of 
the Frama-C function Project.on which is often better to use than 

Hope this helps,
