| Summary | 0001000: Evaluation in the logic can cause crashes | ||||||||
| Description | Evaluation in the logic sometimes causes the warning "using size of void". Worse, this can lead to crashes, as e.g. do_cast raises assert false when it encounters something of type void. It is not clear how one goes from something that has type void* to something that has type void, but this definitely happens. | ||||||||
| Steps To Reproduce | This example can be used to cause the apparition of the warning frama-c -val -then -print void main (int i) { int x=1; while(1) Frama_C_memcpy((void *)&x, (void const*)&x, i); } The generated assertion cast the pointer to void*, then does arithmetic on it. This is incorrect. | ||||||||
