   I have review your code and core dump info carefully. It may be a little difficulty. 
   1. Adding rollup should not call LinkedSchemaChange Class. Because LinkedSchemaChange will not writer new data but create a hard link instead. It is not the semantics for adding rollup.
   2. CHECK in add_column_statistics is valid aside from LinkedSchemaChange. A new method should to be figured out to address this problem.
   I will reproduce this bug in my machine, and help to address this.
