FIX: Rebuilding a nonclustered index to add columns by using CREATE INDEX with DROP_EXISTING=ON and ONLINE=ON causes blocking

Symptoms

You rebuild a non-clustered index by using CREATE INDEX together with the DROP_EXISTING=ON and ONLINE=ON clauses to add a new column to that non-clustered index in SQL Server 2012 or 2014. If you add a new column to the nonclustered index, you may encounter blocking in a different SPID when write operations such as INSERT or DELETE are performed on the same underlying table during the index rebuild period.
