From: Aleksei Guzev Date: 2001-06-29T11:42:58+09:00 Subject: [ruby-talk:17041] Building extension. I mentioned earlier I have problems building my extensions. The problem was while I tried "rb_define_class" the interpreter aborted with segmentation fault. That was the case while I used some "rb_c*" class as Parent. As soon as I pass 0 instead of rb_cObject it works pretty well. What's wrong?
