Summary: Dialplan error: fail to build rule

Initial Comment:
Using postgres and opensips 1.6.4

When starting/restarting opensips I got this message:
...
DBG:dialplan:build_rule: building subst rule
ERROR:dialplan:build_rule:  values 5 is NULL - not allowed
WARNING:dialplan:dp_load_db:  failed to build rule -> skipping
...

The dialplan contains only one row:
 id | dpid | pr | match_op |       match_exp       | match_len | subst_exp | repl_exp | attrs  
----+------+----+----------+-----------------------+-----------+-----------+----------+--------
  8 |    1 |  0 |        1 | ^[a-zA-Z][0-9A-Za-z]+ |         0 |           |          | usrloc
(1 row)

Message:
After some investigation I've checked /modules/dialplan/dp_db.c

It seems the problem is an extra conditional in 1.6.4:
--- opensips 1.6.2 ---
#define GET_STR_VALUE(_res, _values, _index)\
        do{\
                (_res).s = VAL_STR((_values)+ (_index)).s;\
                (_res).len = strlen(VAL_STR((_values)+ (_index)).s);\
        }while(0);
--- ---

--- opensips 1.6.4 ---
#define GET_STR_VALUE(_res, _values, _index)\
        do{\
                if ( VAL_NULL((_values)+ (_index)) ) { \
                        LM_ERR(" values %d is NULL - not
allowed\n",_index);\
                        goto err;\
                } \
                (_res).s = VAL_STR((_values)+ (_index)).s;\
                (_res).len = strlen(VAL_STR((_values)+ (_index)).s);\
        }while(0);
