Date Posted: Mon Oct 14, 2013 9:13 pm Subject: Built release source 0.8.20B - Sigfault

First off, system stats
Ubuntu 13.04
gcc (Ubuntu/Linaro 4.7.3-1ubuntu1) 4.7.3
GNU Make 3.81

I got it to compile, added in missing SQL calls to the database, it ran, was able to make a character that got instantly advanced to top level. Was in game for 5 minutes then suddenly it sigfaults. Trying to log into that character again afterwards sigfaults. Example

Login: Kator
(disconnected and output in shell shows sigfault)

GDB output follows for sigfault after login name entry,

Code Referenced in this dump

Code:

MYSQL_ROW row;
char *trid = NULL;
static nodeStruct<struct> *temp, *next;

res = mysql_use_result(mysql);

GET_OBJ_VAL(OBJ, 5) = time(0);
GET_OBJ_VAL(OBJ, 6) = GET_OBJ_VAL(OBJ, 5);
} else if (GET_OBJ_VAL(OBJ, 5) <time>carried_by && IS_NPC(OBJ->carried_by))) {
GET_OBJ_VAL(OBJ, 1) -= number(0, 3);
GET_OBJ_VAL(OBJ, 5) = time(0);
if (GET_OBJ_VAL(OBJ, 1) < 0)
GET_OBJ_VAL(OBJ, 1) = 0;
}
continue;

Any idea why this is happening?

	The second one can be easily fixed by putting an entry into the trideo_broadcast table. Does the first one still crash after logging back in?

Next issue, added a null entry into the trideo table 0,0,0

still getting the following when I log in with a existing character. (still crashes too after a bit when I log in)

Code:
