Description
If we have auto_increment field in the table, and we insert there a few rows using parameter array, and we have indicator array set for the auto_increment field, and for some row indicator value is set to STMT_INDICATOR_NULL or STMT_INDICATOR_IGNORE, for all subsequent rows server insert values like if same indicator value was set for them, too. i.e. it auto-incremented values instead of values specified in bound array.
I don't think C/C can be here to blame - I traced execution, and things look sane. Besides same error is not exposed with 10.2 server.
I am not sure if that is "major" issue, as this does not look like very probable scenario, but on other hand c/odbc testcases have it. Besides I don't think it's very hard to fix.
Below is short program to repeat it
