I have 1.6.0-0ubuntu14.2 and installed the corresponding source package
from the distro. I copied across to tigervnc svn tree (I did a clean
pull a couple of days back but this issue seems to be happening the
same on 1.0.1 1.0.92 built from Antoine's tarball and two day old svn.
which identifies itself as 1.0.90)
BTW wouldn't be helpful if the server reported the build number ?
I patched it with xserver16.patch which it did OK with slight offsets on
each hunk.

The most recent build was done with the following configure , note the
hal problem no longer showing.
cd unix/xserver
./configure CFLAGS="-O3" CXXFLAGS="-O3" \
--prefix=/usr \
--disable-xvfb --disable-xnest --disable-xorg \
--disable-xinerama --disable-composite \
--enable-glx --enable-glx-tls

(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(Also tried -O2 , same thing.)
Here's dmesg for the two crashes. First is on :1 , second on :0 . In
both cases I just log in, open a image in gimp and click on the canvas.

Do you think the i915 errors are relevant to this issue? They are seen
here as the server restarts after the crash.
Thanks
