Hi qazmlp,

Neither is this order guaranteed nor is this order used by all systems
today...

Just think about how the dynamic loader works, if you use
   dlopen() dlsym() within a prog... it's quite obvious that
   text-segs and data-segs will appear mixed...

If you have access to a linux-system have a look
   at /proc/some_pid/maps
   ( cat /proc/XXXXX/maps ) ... replace XXX with a legal
     pid )

regards ... rainer
