crashes server Check for null value is reliable only after calling some of the val_xxx() methods. If the val_xxx() method is not called the null_value flag will be set only for certain types of NULL values (like SQL constant NULLs for example). This caused a crash while trying to dereference a NULL pointer that is returned by val_str() for NULL values. Fixed by swapping the order of val_xxx() and null_value check.
