I have no idea either.  I agree there *shouldn't* be any connection,
so if ASLR is somehow triggering this then whatever is failing is
almost certainly buggy on its own terms.  But there's a lot of
moving parts here (mumble libxml mumble).  I'm going to wait to see
if it reproduces before spending much effort.
