I''ve just gotten 1.2 properly installed with Lyle''s help. I can now confirm what others have told me: My code segfaults with 1.2. Here''s an abbreviation of the code: class MyMain < FXMainWindow # other methods... def create super # <-- [BUG] Segmentation fault on line 768 # other code... end end In addition, there are several hundred warnings output before that, all of this form: /usr/local/lib/ruby/site_ruby/1.8/fox/glgroup.rb:17: warning: already initialized constant FLT_MIN Any idea what goes on here? If Lyle or anyone else wishes to try the code, it''s downloadable from http://rubyforge.org/projects/tycho I don''t pretend this has any urgency -- it''s just a side project of mine, if a pet one -- but I do want to move it forward eventually. Thanks for any insight... Hal
