I'm using LCR as a GSM <-> SIP interface and I've been trying to figure out why MO calls result in a segfault. I am running openbsc on cdc548cb and LCR on c14326641a built and run on an ubuntu 14.04 64bit.
From what I've investigated so far, the request_uri passed to sofia-sip is
malformed.
Has anyone seen this problem before? Would appreciate pointers.
Here are the full logs and stack trace:

Omar,
We're using LCR a lot and I have never seen this AFAIR. Just as a suggestion - make sure you build and run with the same version of the libsofia and there is no binary incompatibility.
Please excuse typos. Written with a touchscreen keyboard.

As this sounds like an LCR issue, and not an OpenBSC one,please consider posting this to the isdn4linux mailing list, as indicated at the bottom of the page http://www.linux-call-router.de/
So it turns out gcc 4.8 optimizes too aggressively when compiling sofia-sip for LCR. Another symptom of this is that message payloads are missing.
Solution is to compile with "-fno-aggressive-loop-optimizations"

Apparently undefined behavior in the sofia-sip code, debian and now our meta-telephony Yocto layer carry a patch for one routine but in our case there was a silent failure and no segfault. Do you have a backtrace of LCR?
