Using homebrew, from source. I just tried HEAD and had the same result.

Confirmed that the problem is gone when I installed from HEAD. I guess
homebrew just installs by default from a fairly old snapshot.

            <p>Hi,<br>
              <br>
              I have a couple of simple beginner Io questions, so don&#39;t
              unleash the flames just yet.<br>
              <br>
              I&#39;m trying to generate a random value between 0 and 100
              (just for example) with the following code:<br>
              <br>
              rand :=3D Random value(100) round<br>
              <br>
              If I put this even in a file by itself and execute just
              that line, Io never processes the line and just freezes
              right there. If I interrupt execution I get a trace output
              something like this:<br>
