Hi Chandrahas, Thank you for the suggestion. I tried with the guest system of 3 GB and host system of 12 GB. Still the same issue.
Will it help if the gem5 executable is compiled with flag –without-tcmalloc?

If you are simulating a system with 8GB of memory, the gem5 process in your system will try to malloc() 8GB from the host. Depending on the memory availability, your host kernel might outright reject the memory allocation, which is happening in your case. Maybe if you have 12GB in your system, try simulating a system with 6GB memory, it should work.

The kernel that I use has a 3 GB RAM and 4GB swap space. The host system has 12 GB RAM and 4GB swap space. I tried with both atomic and timing CPU’s and used gem5.fast as well as gem5.opt binaries. But, most of the benchmarks from the reference set gets killed with the above setting. src/central_freelist.cc:333] tcmalloc: allocation failed 8192 gem5 has encountered a segmentation fault! However for the same SPEC binaries, system call emulation seems to be just fine. Can anyone help here?
