gem5遇到分段错误，如何修复

Question

所以我正在关注 https://www.gem5.org/documentation/learning_gem5/part1/extending_configs 上的教程 但是当我构建它时，我得到了分段错误。 这是我要编译的代码：

import m5
from m5.objects import *
system = System()

system.clk_domain = SrcClockDomain()
system.clk_domain.clock = '1GHz'
system.clk_domain.voltage_domain = VoltageDomain()

system.mem_mode = 'timing'
system.mem_ranges = [AddrRange('512MB')]

system.cpu = TimingSimpleCPU()

system.membus = SystemXBar()

system.cpu.icache_port = system.membus.cpu_side_ports
system.cpu.dcache_port = system.membus.cpu_side_ports

system.cpu.createInterruptController()
#system.cpu.interrupts[0].pio = system.membus.master
#system.cpu.interrupts[0].int_master = system.membus.slave
#system.cpu.interrupts[0].int_slave = system.membus.master

system.system_port = system.membus.slave

system.mem_ctrl = MemCtrl()
system.mem_ctrl.dram = DDR3_1600_8x8()
system.mem_ctrl.dram.range = system.mem_ranges[0]
system.mem_ctrl.port = system.membus.mem_side_ports

process = Process()

process.cmd = ['cpu_tests/benchmarks/bin/arm/Bubblesort']

system.cpu.workload = process
system.cpu.createThreads()

root = Root(full_system = False, system = system)
m5.instantiate()

print("Begginning simulation")
exit_event = m5.simulate()

print("Done simulating at tick %d because %s " % (m5.curTick(),exit_event.getCause()))

这是我得到的错误：

我正在使用终端命令：build/ARM/gem5.opt configs/tutorial/simple.py 我严格按照他们网站上的教程进行操作，但我遇到了分段错误，有人知道它是由什么造成的，我该如何解决？我已经尝试更新和清除缓存，然后再次构建它，但仍然是同样的错误。我在 oracle VirtualBox 上使用 Ubuntu 20.04。

这也是代码的问题。如原文章所述http://www.gem5.org/documentation/learning_gem5/part1/simple_config/

# for gem5 V21 and beyond
system.workload = SEWorkload.init_compatible(binary)
