Hello, I found that CVC3 version 2.1 says produces a false positive on some VCs related to integer overflow safety. The simple program below is an example where the second integer overflow VC is valid for CVC3 2.1: ----------------------------------------------------- typedef struct { int balance; } purse; //@ requires \valid(p); void credit(purse* p, int s) { p->balance += s; } ----------------------------------------------------- Version 1.5 of CVC3 seems correct on this example ('timeout' for the same VC). - Nicolas -------------- next part -------------- An HTML attachment was scrubbed...
