Title:
  ELF programs with R_386_RELATIVE blocks are badly mapped into memory

Status in libxslt package in Ubuntu:
  Triaged
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Running the Samba autobuild tests on a 15.04 openstack image results
  in a segfault in this command:

  /usr/bin/xsltproc --nonet -o default/docs-xml/manpages/smb.conf.5
  /home/ubuntu/autobuild/b22271/samba/docs-xml/xslt/man.xsl default
  /docs-xml/manpages/smb.conf.5.xml

  I reported this upstream as a bug in xsltproc, but it was found to be
  impossible to reproduce using upstream source on the openstack
  instance:

  https://bugzilla.gnome.org/show_bug.cgi?id=751764

  Comment 8 (https://bugzilla.gnome.org/show_bug.cgi?id=751764#c8) is
  particularly informative.

  The stack trace below shows the segfault actually occurs in libxml's
  xpath evaluation functions. I see no difference between xpath.c in
  upstream 2.9.2 and Ubuntu's version.
