In that case, please also verify that your kernel configuration has enabled 
XATTR_PAX. See, for example, 
<https://wiki.gentoo.org/wiki/Hardened/PaX_Quickstart>. If you have a 
superhardened kernel that refuses to disable ASLR under any circumstances, then 
you'll need to build Emacs with './configure CANNOT_DUMP=yes', something I can't 
recommend for production until we get the pdumper branch merged in.
