something's weird on your system. it seems that /usr/bin/X11/X
and /usr/bin/X11/XFree86 are different files (vs. being
symlinked), can you confirm it? on X i see SEGMEXEC enabled,
whereas on XFree86 i don't (randomization was enabled on both
however). as for why XFree86 crashed, i have no idea, it seems
to have run for quite a long time at least. can you enable
coredumping, and get/analyze one (instructions were posted on
this list a while ago)?
