The xserver crashes immediately on me in realloc. So far all the
information I can get is a backtrace and event messages (this is just
after attempting to launch "xev" which caused weston to run Xorg):
I recompiled with --enable-debug but there is hardly any more information:

Any ideas on how to perhaps get the x server running in a debugger? I
tried changing the launch line to "gdb --args Xorg ..." but it did not
work because it appears the tty is disconnected.
Since this is memory corruption it may be that running valgrind might
find something?
Also it may be a good idea if weston gave up trying to run the X server
if it crashes more than a few times. For me it runs and crashes
continuously (and quite rapidly) until I kill weston.
