It looks like you are using the master branch. I think Eli is worried mor= e=20 urgently about the emacs-25 branch. For emacs-25 with bleeding-edge glibc= , I=20 would expect: Should Emacs use the GNU version of malloc? yes Should Emacs use a relocating allocator for buffers? yes Should Emacs use mmap(2) for buffer allocation? no because emacs-25 will compile both gmalloc.o and ralloc.o on such a platf= orm.
