Same results on x86_64 darwin10. Note however that the alsr in Lion is supposed
to be
more exhaustive than that in previous releases. It seems from the discussion
at...
http://www.0xcafebabe.it/2011/10/15/on-macos-10-7-dyld-randomization/
http://gdtr.wordpress.com/tag/aslr/
that prior to Lion, the dyld image base wasn't randomized for -pie.
