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