SYMPTOMS

If a "DEBUG" build is performed of an ESQL/C application that uses the "Edit and Continue" technology introduced by Microsoft Visual C++ 6.0, an unhandled access violation (AV) may be encountered in Sqlakw32.dll when the application attempts to connect to the SQL Server using the EXEC SQL CONNECT TO statement.

WORKAROUND

To work around this problem, disable the "Edit and Continue" functionality of the application by doing either of the following:

• If you are performing a "DEBUG" build of your application from the command line, change the /ZI compiler option to /Zi.
