主题： Re: [gem5-dev] Segmentation fault: UnderSituation
PhysicalMemory(range=AddrRange("4096MB") and Ruby
Are you running on a 32 bit computer? If so, the allocation of the array
gem5 is using for simulated memory is probably failing. You'd want to
use a smaller memory size or move to a 64 bit computer.

Hi,
When I set the ruby parameter, and physmem is set like "PhysicalMemory(range=AddrRange("4096MB"))" or
"PhysicalMemory(range=AddrRange("8192MB"))" , there exists "Segmentation fault". However, it is
alright if I change the size of memory to numbers other than multiples of 4096, just like 4095, or 8191.
Currently, I have no idea about why this happens.

Can you post more details like -- where the segmentation fault happens
(use gdb), the ISA in use, whether you are using SE or FS mode?
