Assume that you run DBCC CHECKDB command against a table in Tempdb in Tempdb Memory-Optimized Metadata mode in SQL Server 2019. If the table was created in the same transaction(e.g. within an explicit BEGIN TRAN … COMMIT TRAN) as that of DBCC CHECKDB, an access violation may occur when you attempt to fetch the Index Allocation Map(IAM) page of the table.
