Re: SPI_getvalue gives a core dump

This is what i set my tupdesc to. => tupdesc = trigdata->tg_relation->rd_att;
i am using the code like this. the do_log function to log the flow. it gives all correct until it reaches
the line :-
disposition=SPI_getvalue(trigdata->tg_trigtuple, tupdesc, 13);
do_log("Got disposition"); ======> it stops logging from here.

do_log("Entered the main trigger logic"); =========> success
if (TRIGGER_FIRED_BEFORE(trigdata->tg_event)) when = "before";
else when = "after ";

tupdesc = trigdata->tg_relation->rd_att;
if ((ret = SPI_connect()) < 0)
do_log("SPI_connect failed");
else {
sprintf(logs,"SPI_connect success, fired %s",when); ======> success
do_log(logs);
}
ret = SPI_exec("SELECT count(*) FROM ast_cdr", 0);

if (ret < 0){
sprintf(logs, "trigf (fired %s): SPI_exec returned %d", when, ret);
do_log(logs);
}

/* count(*) returns int8, so be careful to convert */
i = DatumGetInt64(SPI_getbinval(SPI_tuptable->vals[0], tupdesc, 1, &isnull));
sprintf(logs, "trigf (fired %s): there are %d rows in ast_cdr", when, i); ====> success
do_log(logs);

disposition=SPI_getvalue(trigdata->tg_trigtuple, tupdesc, 13); =====> failed.
do_log("Got disposition"); ===============> doesnot reach here.

With warm regards.

================== it fails here because i tried to get logs before this
statement and it succeeded.
