Assume that you create a memory-optimized table in SQL Server 2014. Then, you submit a query against the table, and the query specifies a hint that is not recognized by SQL Server. For example, you submit the following query:

SELECT * FROM dbo.ShoppingCart (non_existing_hint) WHERE ShoppingCartId = 1;

In this situation, SQL Server may crash, and you receive the following error message:

Msg 3624, Level 20, State 1, Line 27
A system assertion check has failed. Check the SQL Server error log for details. Typically, an assertion failure is caused by a software bug or data corruption. To check for database corruption, consider running DBCC CHECKDB. If you agreed to send dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update might be available from Microsoft in the latest Service Pack or in a Hotfix from Technical Support.

After you install the update, SQL Server doesn't crash in this scenario, and you receive an error message that looks something like:

Msg 10794, Level 16, State 86, Line 26
The table option 'xxxxx' is not supported with memory optimized tables.
