Hello,

what version do you have? If it is for 3.0, please register a bug at:
http://sip-router.org/tracker/

In 3.0 the crash is at:

 186                 case HDR_REFER_TO_T:
 187                         free_to(hf->parsed);
 188                         break;

I am out of the office without my linux box these days to be able to check more. Maybe some other devel can look a bit at it.

Thanks,
Daniel
