Maybe this is another bug?

[Dave Sworin]

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
