Hello Ciro Santilli, I can't reproduce on master, because I want to simulate a ScratchPad Memory in gem5.
I download the gem5 from "https://github.com/markoshorro/gem5-spm"; ,but I don't know where files different from gem5 master. I can tell you that my compiler is gcc 6 and OS version is ubuntu 16.04.5 LTS. Before I use this gem5-spm, I have some experience to use gem5 master, and can successfully build full system. I will try to run through GDB, get the backtrace.
