We use TYPE's within the RuleGen product, and remember that we have run into the very same ORA-00600 that you mention. The issue was in the area of automatic re-validation of objects whenever RuleGen 'create-or-replace'd an existing dependent object. We received a backport fix for this issue for 9.2 (two years ago). We've not had this issue in 10.2, nor in 11.1.
