The virtual table of the interpreted class To be precise, there are 2 problems here. 1) First one is as Rene described, virtual table problem. There is no compiler independent way of solving this issue. 2) Inheriting compiled class from interpreter should work if you do not override virtual function in interpreted class. Cint supports this feature. However, because of operator new/delete complication, doing this causes crash in ROOT/CINT. I do not know why we can not resolve this. Masaharu Goto
