=== Description ===
use $sel() in event_route from evapi module will cause segfault and kamailio crash.
=== How to re-produce ===
--- Step 1. kamailio.cfg: ---
# --- evapi params --- #
loadmodule "evapi.so"
modparam("evapi", "bind_addr", "127.0.0.1:8448")
modparam("evapi", "netstring_format", 1)
modparam("evapi", "workers", 4)
# --- set a custom options outside any route block
self.MYIP = "1.2.3.4"
# --- set event_route for evapi and invoke $sel; both route will segfault and crash
event_route[evapi:connection-new] {
xlog("L_NOTICE", "[ROUTEDEBUG][evapi:connection-new] new connection
from $evapi(srcaddr):$evapi(srcport)");
xlog("L_NOTICE", "[ROUTEDEBUG][evapi:connection-new] TEST sel:
$sel(cfg_get.self.MYIP)");
}
event_route[evapi:message-received] {
xlog("L_NOTICE", "[ROUTEDEBUG][evapi:message-received] test sel:
$sel(cfg_get.self.MYIP)");
}
--- 2. try connect to evapi ---
You can use any client to try to connect or send message.
in bash, you can just use the following command to connect to and send a message:
exec 3<>/dev/tcp/127.0.0.1/5014; printf "5:Hello," >&3;

Can you try to generate the core dump file and attach here the backtrace from gdb?
To get the core, before running kamailio, do:
```
ulimit -c unlimited
```
Then start kamailio as root and reproduce the issue.
Having the backtrace will help to identify faster the exact part of the code crashing.

I am not sure is this the information you need:
I issue command:
`ulimit -c unlimited; /home/pkg/kamailio/sbin/kamailio -f
/home/pkg/kamailio/etc/kamailio/kamailio.cfg -P /var/run/kamailio/kamailio.pid -m 1024 -M
1024 -u root -g root -w /home/corefiles`
then
`gdb /home/pkg/kamailio/sbin/kamailio /home/corefiles/coredump.20150812`
# OUTPUT

I tried to reproduce, but in my case it printed <null>, it didn't crash.
However, it was an issue because the cfg var values were not updated. In your case might
have been some invalid default value there, resulting in a crash.
I pushed a patch to fix it -- can you test with commit
4404f75cf194e8fd727c2ffaeeea41d2193decf6 ?

**Nice, it works and won't crash anymore. Thanks!**
For the further readers who has same problem and couldn't apply this patch
temporarily,
**below is my workaround before this patch:**
1. load htable module
2. wrap a event route using htable:mod-init exported from htable
3. use $shv to substitute $sel cfg variables as cross-process global setting
4. then you can use $shv in un-patched evapi event_route
( or other modules which has similar situation, especially when async jobs to a
non-main-sip process. )
```
loadmodule "htable.so"
event_route[htable:mod-init] {
$shv(MYIP) = $sel(cfg_get.self.MYIP);
}
```
