I also use embedded cling , and it crash my program when try to use class with virtual function.
ACLiC (which provides support for the ++) is an extension only present in ROOT.
Note that the example works fine on linux. Support for cling on Windows is not yet complete (so we expect still a few unexpected issues), we need to investigate this issue.
