From: Idan Sofer Date: 2003-01-07T18:17:31+09:00 Subject: unknown data type 0x28 I would like to ask, what is usually the cause of this error: [BUG] rb_gc_mark(): unknown data type 0x28(0xbfff9da8) non object ruby 1.6.7 (2002-03-19) [i386-linux] Aborted From what I've found in the archives I understand(As I suspected) it has to do with bug in my C extension code, but i havn't found exact details. One odd thing is that the whole thing is quite random, there is no way I can predict when it will occur, and it never appeared in stress tests i've done for some reason. Idan.
