I don't think this check verifies what you want it to verify... you need to order it like this:


```
// CHECK-NOT: {{\s*}}tail call void @__sanitizer_dtor_callback
// CHECK: {{\s*}}call void @__sanitizer_dtor_callback
// CHECK-NOT: {{\s*}}call void @__sanitizer_dtor_callback
```

or better yet:


```
// CHECK: {{^ +}}call void @__sanitizer_dtor_callback
// CHECK-NOT: call void @__sanitizer_dtor_callback
```
