| 5 | Currently the analyzer with basic store will report false alarm for such code: |
| 6 | |
| 7 | p[0] = "/bin/sh"; |
| 8 | p[1] = NULL; |
| 9 | |
| 10 | execv(p[0], argv); |
| 11 | |
| 12 | This is because BasicStore "collapses" all elements of an array into their base |
| 13 | region. BasicStore should return UnknownVal() when getLValueElement. But that |
