Hey, I haven't tried to replicate this segfault myself, but it may be related to this segfault we've encountered before: https://gem5.atlassian.net/browse/GEM5-782. We haven't really found the root cause of this problem yet.
If this is the same issue, it can be overcome by compiling gem5 to it's "debug" build variant. I.e., recompile with `scons build/ARM_MESI_Three_Level/gem5.debug`, then use the `build/ARM_MESI_Three_Level/gem5.debug` instead of the `gem5.opt` one. Please let me know if this does or does not work. As a minimum I'd like to know if this is the same error as GEM5-782. Kind regards, Bobby -- Dr. Bobby R.
