FIX: Access violation occurs when you run and then cancel a query on distinct count partitions in SSAS


Consider the following scenario:
  • You are using Microsoft SQL Server Analysis Services (SSAS). 
  • You run a query on the partitions that contain distinct count measures.
  • You cancel the execution of this query.
In this scenario, an access violation may occur, and a mini dump file is generated at the same time.
This issue was first fixed in the following cumulative updates for SQL Server:

Cumulative Update 8 for SQL Server 2014 SP1

Cumulative update 2 for SQL Server 2014 SP2
