Hello,
I wrote a if condition below this line to know where dtp->prev was being
initialized.
dtp = (dbt_table_p)shm_malloc(sizeof(dbt_table_t));
*if (dtp->prev){
LM_DBG("dtp->prev was initialized")
}*
Analysing the trace of kamailio, the condition is true only to subscriber
table. I can't get understand this behavior only subscriber table because to
others tables (location, dispatcher and version) the condition is false.
PS: I'm doing this analysis to understand the core generated in db_text
module described in the previous e-mails.
Best Regards

Hello,
the latest 3.1 branch as in db_text/dbt_tb.c following line:
dtp = (dbt_table_p)shm_malloc(sizeof(dbt_table_t));
Where is the line you refer to dpt->prev? Can you copy&paste it here.
Cheers,
Daniel

Hello ALL,
Someone knows why at line 149 in .../kamailio-3.1.2/modules_k/
db_text/dbt_tb.c the shm_malloc function sometimes allocates memory to
dtp->prev but sometimes doesn't?
I'm asking this question because when the subscriber table is being loading
to shared memory in db_text module, dtp->prev is allocated but on version,
dispatcher, location table it doesn't... Analysing the source code I can't
see any reason to this behavior.
The allocation of dtp->prev to subscriber table is generating a core at
db_text module.
Best Regards
