Hello,
It seems that if I put the following (bad) code in a file and try to
compile it, that gprolog goes into an infinite loop. I have only tried this on
Fedora Core 4. A predicate without arguments is fine, but not with empty
parentheses. This is fine with me. However, I am an old C programmer and did
this by accident in a much larger file. I'm not sure this is a bug, but maybe
you want to fix it. By-the-way, the problem does not occur if a predicate does
not preceed it in the file. For example, without the predicate mypred/1 below,
the bug does not occur. Can you reproduce this problem also?
Dave

mypred(ARG1) :-
ARG1 is 2 + 4.
test_case() :-
true.
