| 6 | ; The test case is buggy, it supposed to check that we reject memcpy with vector |
| 7 | ; pointer arguments. Now we don't reject such memcpy and the test case would |
| 8 | ; fail if it was correct. Because it used the wrong signature for memcpy (the |
| 9 | ; last isVolatile argument was missing) it was rejected by the verifier and |
| 10 | ; didn't fail. Fix the memcpy signature and mark it as an expected failure |
| 11 | ; for now. |
