Failed assertion on build/opt/timing_event.h:161: startCycle < minStartCycle (17DDRMemoryAccEvent)
I started experimenting with running SPEC benchmarks on zsim but I always run into this error (on large simulations):

Any ideas what might be causing this?
Thanks
are you running with a prefetcher? prefetchers do not work with bound/weave

Actually, no. I am running my experiments with default value of prefetcher, which is no.
isPrefetcher = false;
