You have to try and debug it further to narrow down the exact operation gem5 seems to be doing wrong (--debug-flags ExecAll, GDB into guest).
This could be easy to spot, or extremely difficult if the divergence happened way earlier in execution before the crash, but I don't see an alternative. One possible approach especially for single threaded execution is to try and compare QEMU ExecAll logs to QEMU instruction traces.
