Are you linking with gold at all? The debian-sparc folks found a nasty
bug which would cause random segfaults on a lot of apps such as systemd:
https://sourceware.org/bugzilla/show_bug.cgi?id=18855. I believe the fix
is now upstream so if you are using gold then it might be worth a quick
check of your exact binutils version.
