Hi,
  finally found some time to look at this issue.

Basically the sequence become:
1- do a query to get row format
2- initialize bcp
3- do a query for identity inserts
4- fill the bcp columns information with information from step 1.
The problem is that the step 3 clear the information needed in step 4.
Moving the query at step 1 after 3 (I put after bcp_control and before
bcp_columns) fix the issue. Not sure about datacopy.

Can you test master (or tomorrow nightly snapshot) ?
