Simon,
Recent kernels do notify application segfaults on the kernel console
(via a handler of the associated MMU processor trap). This is a way for
administrators that something is going wrong on the machine. Otherwise
the crash is only visible from the user's context & the disk may fill-up
silently with core dumps.
The exact format in the syslog is kernel-dependent & hence differs from
Debian & RHEL (the 2 OS's I have observed this message on).
There is a similar messagefor un-aligned memory access.

Hi,
Can you please run the same test from gdb ?
I'm a but surprised with this segfault message coming from the kernel.

do other users of linphonec have the same issue ?
With xwindow linphone starts fine but I can't hear my correspondant and
him can't hear me neither.
Thanks for any advice.
