Ok, thank you! I can use the latest build.<div>--- nadeem On Tuesday, January 27, 2015, Matthew Flatt <<a href="mailto:mflatt@cs.utah.edu">mflatt@cs.utah.edu</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Yes, it's a bug in v6.1.1. I've just pushed a repair for the next build. Do you need a workaround for v6.1.1? Your variant that sets `sandbox-namespace-specs` is what I would have tried; unfortunately, that runs into a second bug in v6.1.1 that I recently fixed. If you need a workaround other than using the next snapshot, I can look harder for one. Thanks for the report!
