| Summary | 0002414: Mk_addr not defined in Memory.v (coqwp via why3ide) |
| Description | Memory.Mk_addr is needed for Coq proofs but not in Memory.v (it *is* present in Memory.why).
As a consequence, Coq fails to compile the generated proof scripts for a null pointer check:
> Error: The reference Memory.Mk_addr was not found in the current environment. |
| Steps To Reproduce | cat <id.c
/*@ requires \valid(p);
ensures *p == \old(*p);
*/
void id(int* p)
{
int tmp;
if (p == (int*)0) return;
tmp = *p;
*p = ~~tmp;
}
