I have seen problems to build the HOL image on my new macOS Sierra test 
machine (which is a bit underpowered). It helps to provide more initial 
heap space, e.g. like this in etc/settings:

ML_OPTIONS="-H 1000"

Alternatively, it also helps to build with -o threads=1.

Maybe this is a symptom of Mac OS X memory management problems that 
we've occasionally seen in recent years.
