Hi Michael,
Interesting, I can't reproduce on my machine.
I suspect may due to excessive memory consumption on your system, is it
possible? Could you have a run monitoring it? Maybe also having a look
into 'dmesg' output may give some info about why the process got killed.

Yeah I think this is a bug in the benchmark. This is compiled at speed
3 and the programmer should be responsible to "garbage-collect-maybe" in
hot loops if this is required.
If this theory is correct you should see the issue disappearing adding
~(declare (speed 2))~ to `elb-pidigits'.
