[SR-Users] Kamailio Unexpectedly Terminating

[Daniel-Constantin Mierla]

Hello,

I committed a patch that should make it work when realm_prefix is not 
set for registrar module:

http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=d42379da90f2ec87cb5dbb00ebb563c7528ec910

For the moment I have no idea why SIGBUS is triggered, i tried to access 
the structure directly, not via defines, and there is still a problem 
when realm_prefix is set. It's ok accessing the .len field but not .s of 
the same structure. The field .s is the first, making me think it's not 
alignment issue, or it is something very specific to this system.

Overall, I am not familiar with sparc/solaris systems, maybe if you send 
here full details about OS version, architecture and CPU type, others 
using similar systems can give hints.

Jason reported that on solaris with x86, this problem was not encountered.

Cheers,
Daniel
