--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Complete testcase:
#include <stdlib.h>
struct S1 {
unsigned int x;
float y;
struct S1 *z;
};
struct S1 *f1(void) {
struct S1 *p = malloc(sizeof(p)); // diagnostic required
return p;
}
It would probably make sense to not only warn for malloc, but also for other
functions with __attribute__((malloc)) and __attribute__((alloc_size(n))) where
n!=sizeof(*p). That would also help for xmalloc and similar wrappers in gcc and
glibc.
