Hi! We are constantly running into this issue on sparc64 as well.
I have already updated the kernel to 4.3.3 from unstable as well as tried the patch that Peter De Wachter suggested for docbook-xsl as well as changing the permissions for /dev/shm, to no avail. xsltproc still randomly segfaults: root@test-adrian1:~# chroot /srv/sid-sparc64-sbuild/ root@test-adrian1:/# cd debian/libxslt/systemd-228/man/ root@test-adrian1:/debian/libxslt/systemd-228/man# /usr/bin/xsltproc -o man/halt.8 --nonet --xinclude --stringparam man.output.quietly 1 --stringparam funcsynopsis.style ansi --stringparam man.authors.section.enabled 0 --stringparam man.copyright.section.enabled 0 --stringparam systemd.version 228 --path './man:../man' ../man/custom-man.xsl ../man/halt.xml Segmentation fault root@test-adrian1:/debian/libxslt/systemd-228/man# /usr/bin/xsltproc -o man/halt.8 --nonet --xinclude --stringparam man.output.quietly 1 --stringparam funcsynopsis.style ansi --stringparam man.authors.section.enabled 0 --stringparam man.copyright.section.enabled 0 --stringparam systemd.version 228 --path './man:../man' ../man/custom-man.xsl ../man/halt.xml <== here it worked root@test-adrian1:/debian/libxslt/systemd-228/man# /usr/bin/xsltproc -o man/halt.8 --nonet --xinclude --stringparam man.output.quietly 1 --stringparam funcsynopsis.style ansi --stringparam man.authors.section.enabled 0 --stringparam man.copyright.section.enabled 0 --stringparam systemd.version 228 --path './man:../man' ../man/custom-man.xsl ../man/halt.xml Segmentation fault root@test-adrian1:/debian/libxslt/systemd-228/man# /usr/bin/xsltproc -o man/halt.8 --nonet --xinclude --stringparam man.output.quietly 1 --stringparam funcsynopsis.style ansi --stringparam man.authors.section.enabled 0 --stringparam man.copyright.section.enabled 0 --stringparam systemd.version 228 --path './man:../man' ../man/custom-man.xsl ../man/halt.xml Segmentation fault root@test-adrian1:/debian/libxslt/systemd-228/man# Frankly, I am very much convinced that xsltproc is broken. It's apparently happening quite often that xsltproc segfaults as the below reports on different architectures and operating systems show: > https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1471029 > https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203250 > https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=195044 > https://forums.gentoo.org/viewtopic-t-248184-start-0.html > https://trac.macports.org/ticket/24060 I find it rather frustrating that libxslt upstream does not consider this a bug and hence closed the related bug report: > https://bugzilla.gnome.org/show_bug.cgi?id=736077 I'm currently out of ideas and I would appreciate it a lot if anyone could suggest something else to try.
