Regression with SWI-Prolog (threaded, 64 bits, version 8.3.20) on a Mac

SWI-Prolog (threaded, 64 bits, version 8.3.20)

I am doing several iterations of “edit some source”, make, run queries.
After some iterations, Prolog will produce the following error trace
Guess this is a regression in the current version…

?- make.
