-R --random
When assigning addresses to libraries, start with random
address within architecture dependant virtual address
space range. This can make some buffer overflow attacks
slightly harder to exploit, because libraries are not
present on the same addresses accross different
machines. Normally, assigning virtual addresses starts
at the bottom of architecture dependant range.
