Sujet: Re: [Dng] Dng Digest, Vol 3, Issue 65
Not wanting to advocate for Go or statically linked binaries ( unless there
is a library version conflict ).

Question about ASLR:
Matteo Panella writes, "but that [ASLR?] does *not* change the overall
layout of executable pages - again, it's set in stone by the compiler,"

besides, "overall layout." Why cant the pages of a statically linked binary
be just as randomized by the OS as a dynamically linked binary?
