Check the StoneDB5.6,it crashed likewise.

The PPM2 does not work, the code for PPM2 seems not completed, and code is not from some third-party. If we want to support it , we need to know what is PPM2, how it works in principle, and research the code to learn how it implents, after that we can start to slove the bug . It is a feature task.

change it to a feature as customer rarely use this compress algorithm.
