You have chosen to enable "force-reg" in USE. From the GForth manual
(http://www.public.iastate.edu/~forth/gforth_141.html):
"This feature not only depends on the machine, but also on the
compiler version: On some machines some compiler versions produce
incorrect code when certain explicit register declarations are
used. So by default -DFORCE_REG is not used."
