Thanks Gerzhoy for your email.
The code is attached here. I got the error for some of benchmarks not for all.
I used this command to run the code
/home/abdkhail/aa/gem5/build/X86/gem5.opt --outdir=/home/abdkhail/aa/gem5/o1
/home/abdkhail/aa/gem5/configs/example/spec06_config.py -I 1000000000
--benchmark=povray --benchmark_stdout=/home/abdkhail/aa/gem5/o1/povray.out
--benchmark_stderr=/home/abdkhail/aa/gem5/o1/povray.err --cpu-type=DerivO3CPU
--caches
I observed when i changed --cpu-type=DerivO3CPU to another CPU type it is
working fine but i have to get the stats output of this type
--cpu-type=DerivO3CPU .
Best Regards

Subject: Re: [gem5-users] gem5 has encountered a segmentation fault!
It looks like gem5 itself had a segfault.
Did you change the simulator code itself?
If so I would look at whatever code you added to see if you referenced a memory
address you don't actually have access to.
You could run the simulator in GDB as well and add breakpoints to debug further.
best regards,
Dan Gerzhoy

Hello Everyone,
I am currently working on running the benchmark on gem5 and some of them gave
me the below error.
Any help in this regard? I would really appreciate that.
