Error: drcachesim -offline -use_physical

Created by: arkodutt

Hi,

I am very new to exploring dynamorio. So these might seem pretty basic queries. I am trying to create a readable memory trace file from any application containing the physical address translations from pagemap virtual addresses. I found the dynamorio useful for creating such an output by using drcachesim client. Got an error while executing "./bin64/drrun -t drcachesim -offline -use_physical -- ls"

Assert failure Error : /dynamorio/clients/drcachesim/tracer/instru_offline.cpp:192: false ().

Two queries -

1. I saw this type of issue reported before, but couldn't decipher how to fix it. How to fix it?
2. I wish to have an understandable/readable text-mode file containing the physical addresses, and not binary trace dump. Is there any existing way of getting it?

Thanks, Arko
