That's a tough question. I thought about this, and the argument for
showing the fixed up address is that if someone does the math with
symbol offsets from e.g. objdump, the result will be consistent with
what gdb shows.
On the other hand side, why would anyone do this? that's exactly what
this gdb script is for. So showing the actual address at which the
memory was allocated gives the user some additional information, and is
also consistent with what cat /proc/modules would show.
At the end of the day, I don't have a strong opinion on this, so if you
think it's better to show the fixed up address, I'll send a v2.
Best regards,
Ilya
