Hi Federico,
The first hit from Google 'how to run command from gdb'
https://ftp.gnu.org/old-gnu/Manuals/gdb/html_chapter/gdb_5.html#:~:text=Use%20the%20run%20command%20to,section%20Commands%20to%20specify%20files).
# gdb
(gdb) file /usr/sbin/asterisk
(gdb) run –gvvvvvvc
Starting program: /usr/sbin/asterisk -gvvvvvc

Can you give me instruction to trap this segfault on starting asterisk?
Like gdb …..asterist –gvvvvvvc

Hi Federico,
Segfaults are 100% not by design. Typically if something seg faulted,
either there is a logic bug or a component mismatch. The you should
definitely be able to use more than one connection (we use multiple
connections with postgres odbc with no issue).
If Asterisk segfaults when using odbc
Try this:
- use ps and get the pid of Asterisk
- run gdb, attach to the asterisk pid
- do something that would cause the seg fault
- get a backtrace (bt) and show all threads backtrace (thread apply
all bt)
if Asterisk segfaults when starting up
Run Asterisk straight from gdb
Wait for segfault, get backtrace, and all threads backtrace

I tested this issue with version 13 and version 18.
In res_odbc.conf, if I add a second, new data source like
[asterisk]
enabled=yes
dsn=asterisk
sanitysql => select 1
isolation => read_committed
username=root
;password=
pre-connect => yes
forcecommit => yes
connect_timeout => 10
negative_connection_cache => 0
max_connections =>500
my odbc.ini
[cdr]
Description = MySQL ODBC Driver Testing
Driver = maria
Socket = /var/run/mysqld/mysqld.sock
User = root
Password =
Database = public
Option = 3
I get, immediately, segmentation fault.
With only one, it works fine.
Is this by design?
