Is the problem you are facing in the gem5 code or your guest-code running in the simulation?
This looks to be a problem in the guest-code. You're calling pointer++ twice, which should, naturally, increment the address by 8. Based on this information, I do not know why the first incrementation fails to print the correct address. -- Dr. Bobby R.
