Watch and see + +Actual Results: +You get two IndexOutOfRangeExceptions + +Expected Results: +You should get two ArgumentOutOfRangeExceptions + +How often does this happen? +Always + +Additional Information: +This occurs because set_Item calls CheckIndex, which does not check to determine if index is +equal to _size (because in most of the contexts from which CheckIndex is called, this is +appropriate). + +The fix is simple, and will be attached momentarily. _______________________________________________ mono-bugs maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-bugs
