### Description :
In the attached file, a function ptr is returning a void* value. This function is used to obtain pointers to int in various contexts (there was initially a difference between them, see issue 1945). WP does not generate any proof obligation, and outputs a warning saying
Cast with incompatible pointers types (source: sint8*) (target: sint32*)
I guess the problem is that void* gets converted to char* somehow (changing machine.sizeof_void for the current architecture does not modify the error message)
