I ran into this problem:

    http://article.gmane.org/gmane.emacs.devel/35276

This fixed it (it was set to 2):

    # echo 0 > /proc/sys/kernel/randomize_va_space

I didn't try setarch -R because I couldn't guess what my arch was to
tell setarch (I tried everything I could think of from "armv7l" to
"ventana").

I'm too lazy to read the whole 2005 thread.  Since etc/PROBLEMS doesn't
mention this issue, only the exec-shield one, I guess this problem was
supposed to be fixed at the time -- so why did I see it today?
