Problem with Ramulator

[zhizunbaowhy]

Hi,
To use ramulator.
I followed README.md

CPU trace Driven
$ cd ramulator
$ make -j
$ ./ramulator configs/DDR3-config.cfg --mode=cpu cpu.trace (here is problem)

tracenum: 1
trace_list[0]: cpu.trace
terminate called after throwing an instance of 'std::invalid_argument'
what(): stoul

I'm using the latest version. And I've already run "git pull".
What should I do?
I would appreciate it if you could help me with the issue.
