Thanks a lot for your help Andi. It clears a lot of gray areas for me.

Well imagine the case, even though very unlikely, where the user would create a program with a pre-initialized stack. This does sound awkward, but it's in the real of the possible. This is the only reason I check the data segment.
Very unlikely, but not impossible ...
Thanks again!
