This looks like a latent bug on the mainline too, just harder to reproduce and
here is a testcase:
struct test {
struct tt
{
volatile int a;
volatile int b;
} t;
};
int main(int argc, char *argv[]){
struct test *p = (struct test *)0x10000000;
struct tt *ptr = &p->t;
ptr->b = 10;
(int)ptr->b;
return 1;
}
