Any idea on the second problem/feature - subcollections not working (or not available) in PLaneT?  Doug <div class="gmail_quote">On Jan 4, 2008 7:27 AM, Matthew Flatt <<a href="mailto:mflatt@cs.utah.edu"> mflatt@cs.utah.edu</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">The JIT flonum problems have been fixed, and the JIT's flonum support is re-enabled in SVN. There's a good chance that your plots will work, now. The JIT bug was leaving the FP stack in a bad state, which mostly affected FP code *not* generated by the JIT (e.g., the FP code in the plot library).
