Sorry.  That was:

     [0] https://godbolt.org/z/ETcxnz4TW

Change

(volatile __typeof__(ptr))(ptr);

for:

(volatile __typeof__(*(ptr)) *)(ptr);

and:

void love_iso(int *x)
{
     __atomic_store_n(cast_volatile(&x), 1,
                      __ATOMIC_RELAXED);
}

for

void love_iso(int *x)
{
     __atomic_store_n(cast_volatile(x), 1,
                      __ATOMIC_RELAXED);
}

Thanks,

Mathieu
