Making sure we're all on the same page, I think the diagnostic should show up
like:
```
extern void free(void *);
extern void *malloc(size_t size);
void t8(void) {
void *p
__attribute__((
cleanup(
free // expected-warning{{attempt to call free on non-heap
object 'p'}}
)
))
= malloc(10);
```
and
```
struct __attribute__((aligned(8))) S {};
void derp(struct S *ptr);
int main(void) {
typedef __attribute__((aligned(4))) struct S TypedefAligned4;
TypedefAligned4 s1;
derp(&s1); // expected-warning {{passing 4-byte aligned argument to 8-byte
aligned parameter 1 of 'derp' may result in an unaligned pointer access}}
__attribute__((cleanup(derp))) // expected-warning {{passing 4-byte aligned
argument to 8-byte aligned parameter 1 of 'derp' may result in an unaligned
pointer access}}
TypedefAligned4 s2;
}
