Description :

A few functions in the value analysis (Eval.initialize_var_using_type, Eval.return_value, Eval.compute_call), as well as Builtins.frama_c_alloc_infinite call the function Cabs2cil.fresh_global. Since it is a global hashtable that is never reset, successive executions of the value analysis will yield different results over time. This causes convergence problems for, eg. fixpoint-based plugins.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
