I was exploring the similarities and differences between the clang and gcc implementations for "counted_by" attribute support and came across the following difference in behavior.
```
#include <stdlib.h>
struct signed_struct {
int b;
int c[] __attribute__ ((counted_by (b)));
} *psigned_struct;
int main(int argc, char *argv[])
{
struct signed_struct *ps = (struct signed_struct *) malloc(sizeof(struct signed_struct));
ps->b = -3;
ps->c[2] = 0;
return 0;
}
```
