On 386 the below code triggered an infinite loop in growslice: x = make([]byte, 1<<30-1, 1<<30-1) x = append(x, x...) Check for overflow when calculating the new slice capacity and set the new capacity to the requested capacity when an overflow is detected to avoid an infinite loop. No automatic test added due to requiring to allocate 1GB of memory on a 32bit plaform before use of append is able to trigger the overflow check.
