Using fast-fwd-user-insns from with multithreaded is not a good idea. from git log "Note: When '-fast-fwd-user-insns' is specified for multi-threaded programs,there might be a deadlock issue in kernel mode due to full-system simulation.MARSS. So use -fast-fwd-insns (that couts both user and kernel instructions) for multithreaded benchmarks."
