Now, Spacemacs loads as well with master.

 Yes, Emacs master builds and works in console (same issue for packages mana= ger, bug #25221) but I have to

echo 0 | sudo tee /proc/sys/kernel/randomize_va_space

 before the build starts otherwise it fails.


Yes, this is needed and = that won't change until unexec is removed from emacs (either replace by= portable dumper or loading everything at runtime).
