I think I know why this is happening but I'll only be able to patch the code tonight. When the ttf library is closed (either explicitly or when SDL:WITH-INIT ends) it free's all font resources. Trouble is when the garbage collector garbage collects a font it also tries to free the font resources. If the garbage collect happens after WITH-INIT... Bang! I'm going to have to add a *generation* counter. Each time the font library is closed the generation counter is increased. Then add a test in the CFFI finalization method to test if the font to be free'd was created in the current *generation*. If it was not then the font cannot be freed. - Luke _______________________________________________ application-builder mailing list [email protected] http://www.lispniks.com/mailman/listinfo/application-builder
