BTW, shouldn't we fix print_buffer() also? do_mem_md() doesn't use memcpy() and the issue with corrupted dumps still remains here. I'm testing a patch to fix it. Will submit it soon.
I though about this, too. But then I decided against it. "md" is intended to to exactly what the user requests - as is, we can easily demonstrate the issue. I consider this an extremely useful debug feature. If I command the memory to be read in units of 32 bits I really mean that. A "fix" ins print_buffer() whould hush up the symptoms, so the problem would be much harder to detect.
Thanks for the explanation, I didn't thought about it. This is indeed a reasonable debug feature.
Best regards, Anatolij
