Sorry missed one undefined type.
Here is the corrected reduced testcase:
```
extern int write1 (int __fd, const void *__buf, int __n)
__attribute__ ((__access__ (__read_only__, 2, 3)));
typedef struct {
struct {
int b;
int c;
} s2;
} S;
void f1(int *a);
int f(S *s )
{
int err;
f1(&s->s2.b);
err = write1( 1, (const void *)&(s->s2), 6);
return err;
}
```
