bug#22662: 25.0.91; unable to compile on debian wheezy

[Sam Halliday]

Hi,

I have a docker image which builds various versions of emacs in a
completely well-defined and reproducable debian wheezy environment:

  https://github.com/ensime/ensime-docker/blob/v1.x/Dockerfile

I wanted to add the pretest to the build list and I added these
instructions after the Emacs section

################################################
# Emacs Pretest
RUN\
  apt-get install -y debfoster &&\
  debfoster -q &&\
  apt-get build-dep -y emacs23 &&\
  mkdir /tmp/emacs-build &&\
  EMACS_VERSION=25.0.91
  curl --disable-epsv ftp://alpha.gnu.org/gnu/emacs/pretest/emacs-${EMACS_VERSION}.tar.xz -o /tmp/emacs-${EMACS_VERSION}.tar.xz &&\
  cd /tmp && tar xf emacs-${EMACS_VERSION}.tar.xz &&\
  cd emacs-${EMACS_VERSION} &&\
  ./configure --prefix=/opt/emacs-${EMACS_VERSION} &&\
  make && make install &&\
  echo Y | debfoster -f &&\
  rm -rf /tmp/emacs* &&\
  apt-get clean


Unfortunately, this failed at `make' with this error

Since this builds for all previous 24.x releases of Emacs in a
completely well-defined and reproducible environment, I suspect that
Emacs has introduced a bug.

I could not reproduce the problem on debian-7.9.0-amd64 (wheezy). Emacs builds 
and runs just fine for me on this platform.

What hardware platform are you using? It's not clear from the email.

Did you try the advice in etc/PROBLEMS? It talks about 'echo 0 > 
/proc/sys/kernel/randomize_va_space' or, if you're on the x86, running 'setarch 
i386 -R make' and building from scratch.

Since we can't reproduce the problem, and since the original reporter does not 
seem to be interested in helping us reproduce the problem, I'm closing the bug.
