[SR-Users] any interest in segmentation fault at startup ?

[Daniel-Constantin Mierla]

Hello,

if you get a core dump, then send the backtrace taken with gdb -- even
better, open an issue on the bugtracker from
github.com/kamailio/kamailio - the template there should guide you on
what details to provide.

On the other hand, can you just try with:

 xlog("L_INFO","route(fixdigits)  @@ $rm - E164 :
sip:$(fU{s.substr,1,0})@$fd");

So no need of string concatenation with +, the variables inside the
parameter for xlog() are evaluated always.

Using expressions for parameters was something added by SER branch in
the past, not sure if all modules are handling that properly.

Cheers,
Daniel
