Thanks, it was easy to spot from the gdb backtrace -- this was due to an issue introduced by commit f775e4000e in master branch. I pushed a fix to it, try again with latest master.

Can you run as root in the terminal:

ulimit -c unlimited

Start kamailio in the same terminal, adding extra parameters '-w /tmp'

Reproduce the case and you should get a core file in /tmp if kamailio crashes. Grab the backtrace with gdb and send it here.

Kamailio just segfault on reply route on SUBSCRIBE?

What to add to compile options to make this message more clear?

Hello,

indeed, I did a rename to make it more clear the purpose of a drop-related function, breaking the use from other modules.

I pushed the commits to fix the issue, try again with latest master.

A bit dumb question - how to specify lua.h file path to make command? It looks in

ls: cannot access /usr/local/lib/liblua*: No such file or directory

ls: cannot access /usr/local/lib/liblua*: No such file or directory

CC (gcc) [M app_lua.so] app_lua_mod.o
