Consider the following scenario:
You have Microsoft SQL Server 2014 installed on a computer.
You create incremental statistics on your table.
You merge partitions of your table multiple times to reduce the number of the partitions by at least 2.
You update the incremental statistics manually or update enough data to trigger the automatic statistics update by compiling a query.
In this scenario, an access violation occurs. Additionally, you receive the following error:
A severe error occurred on the current command. The results, if any, should be discarded.
