SQL Server 2014 Bug - with Clustered Index On Temp Table with Identity Column

Question

Hi,
Here's a stored procedure.  (It could be shorter, but this will show the problem.)
          CREATE PROCEDURE dbo.SGTEST_TBD_20141030 AS
          IF OBJECT_ID('TempDB..#Temp') IS NOT NULL
             DROP TABLE #Temp
          CREATE TABLE #Temp
           Col1        INT NULL
          ,Col2        INT IDENTITY NOT NULL
          ,Col3        INT NOT NULL
          CREATE CLUSTERED INDEX ix_cl ON #Temp(Col2)
          SET IDENTITY_INSERT #Temp ON;
          RAISERROR('Preparing to INSERT INTO #Temp...',0,1) WITH NOWAIT;
          INSERT INTO #Temp (Col1, Col2, Col3)
          SELECT 1,2,3
          RAISERROR('Insert Success!!!',0,1) WITH NOWAIT;
          SET IDENTITY_INSERT #Temp OFF;
In SQL Server 2014, If I execute this (EXEC dbo.SGTEST_TBD_20141030)   It works.   If I execute it a second time - It fails hard with: 
        Msg 0, Level 11, State 0, Line 0
        A severe error occurred on the current command.  The results, if any, should be discarded.
        Msg 0, Level 20, State 0, Line 0
        A severe error occurred on the current command.  The results, if any, should be discarded.
In SQL Server 2012, I can execute it over and over, with no problem.  I've discovered two work-a-rounds:   
1) Add "WITH RECOMPILE" to the SP CREATE/ALTER statement, or 
2) Declare the cluster index in the TABLE CREATE statement, e.g. ",UNIQUE CLUSTERED (COL2)" 
This second option only works though, if the column is unique.    I've opted for the "WITH RECOMPILE" for now.  But, thought I should share.

Hi,
I did not get any error Message:
         CREATE TABLE #Temp
           Col1        INT NULL
          ,Col2        INT IDENTITY NOT NULL
          ,Col3        INT NOT NULL
          CREATE CLUSTERED INDEX ix_cl ON #Temp(Col2)
          SET IDENTITY_INSERT #Temp ON;
          RAISERROR('Preparing to INSERT INTO #Temp...',0,1) WITH NOWAIT;
          INSERT INTO #Temp (Col1, Col2, Col3)
          SELECT 1,2,3
          RAISERROR('Insert Success!!!',0,1) WITH NOWAIT;
          SET IDENTITY_INSERT #Temp OFF;
SELECT * FROM #Temp
OUTPUT:
Col1 Col2
Col3
1 2 3
1 2 3
1 2 3
