BUG: Multiple Calls to bcp_colfmt Fail to Free Memory

• Microsoft SQL Server Programmer's Toolkit, version 4.2

SYMPTOMS

An application that uses DB-Library (DB-Lib) bulk copy (BCP) functions encounters DB-Lib error 10000 after running for a significant amount of time:

Unable to allocate sufficient memory.

CAUSE

DB-Lib incorrectly fails to free memory after multiple calls to bcp_colfmt for the same column during a single BCP operation.

WORKAROUND

For a single BCP operation initiated with bcp_init, call bcp_colfmt only once for each column.

STATUS

Microsoft has confirmed this to be a problem in DB-Library version 4.20.00. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
