I've since found that the trace problem, and all the other strange behaviour
including some on 32-bit x86, disappears if you compile gprolog without
optimization. To do this, start with "./configure --with-c-flags=no"
If I have some spare time I'll try and see which optimization flags are
causing the problem. Not sure why the default setting
is "-O3 -fomit-frame-pointer" when -fomit-frame-pointer, according to the
compiler info, is included in -O1 and above.
