I would expect its the functio that checks the buffer type that has 
signaled a invalid type

check_target_type( target_type )

That checks that the SQL Type is one of the folowing:

switch( c_type ) {
case SQL_C_CHAR:
case SQL_C_LONG:
case SQL_C_SHORT:
case SQL_C_FLOAT:
case SQL_C_NUMERIC:
case SQL_C_DEFAULT:
case SQL_C_DATE:
case SQL_C_TIME:
case SQL_C_TIMESTAMP:
case SQL_C_TYPE_DATE:
case SQL_C_TYPE_TIME:
case SQL_C_TYPE_TIMESTAMP:
case SQL_C_INTERVAL_YEAR:
case SQL_C_INTERVAL_MONTH:
case SQL_C_INTERVAL_DAY:
case SQL_C_INTERVAL_HOUR:
case SQL_C_INTERVAL_MINUTE:
case SQL_C_INTERVAL_SECOND:
case SQL_C_INTERVAL_YEAR_TO_MONTH:
case SQL_C_INTERVAL_DAY_TO_HOUR:
case SQL_C_INTERVAL_DAY_TO_MINUTE:
case SQL_C_INTERVAL_DAY_TO_SECOND:
case SQL_C_INTERVAL_HOUR_TO_MINUTE:
case SQL_C_INTERVAL_HOUR_TO_SECOND:
case SQL_C_INTERVAL_MINUTE_TO_SECOND:
case SQL_C_BINARY:
case SQL_C_BIT:
case SQL_C_SBIGINT:
case SQL_C_UBIGINT:
case SQL_C_TINYINT:
case SQL_C_SLONG:
case SQL_C_SSHORT:
case SQL_C_STINYINT:
case SQL_C_ULONG:
case SQL_C_USHORT:
case SQL_C_UTINYINT:
case SQL_C_GUID:
case SQL_C_WCHAR:
case SQL_ARD_TYPE:
case SQL_C_DOUBLE:

Turn on ODBC tracing and see what is being passed into the call to 
SQLBindCol It may be a type I haven't seen.
