Hi,
Similarly to the results posted by George earlier, the "Final Performance Info" was printed in the mdinfo (see below) and the mdout's (see below) version of the "Final Performance Info" attempts to do an average over 0 steps (which I assume is because last_step_count gets set to current_step when it is called in runfiles before the final call?).
To see what would happen I added a test to prevent an mdinfo flush when there is equality between nstep & total_nstlim at the same time as the mdinfo_flush_interval check in runfiles and that appears to fix things.
Many thanks,

​What is the content of the mdinfo file?
