<div dir="ltr">I have narrowed the problem down to a minimal piece of code. I am attaching two files - main.ss and seedgen.ss. seedgen.ss has mzscheme as the language implementation name. main.ss has scheme as the language implementation. I dont know if running code across different implementation names is supposed to work. The code as is works when "Debugging" is chosen as the dynamic properties for module. The code does not work when "Debugging and Profiling" is selected. If I change the implementation name in seedgen.ss to scheme, the code begins to work. I have to admit I have not read much about modules, so I might be missing something obvious here. <div class="gmail_quote"> On Wed, Oct 15, 2008 at 8:41 AM, Robby Findler <<a href="mailto:robby@cs.uchicago.edu">robby@cs.uchicago.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;"> That sounds like a bug. I tried some simple things and wasn't able to reproduce it, tho. Do you mind sending a (hopefully small) program that illustrates the problem? Also, if you wanted to submit a PR (via the "Submit Bug Report" menu item in the "Help" menu), that would be appropriate.
