I'm seeing the same segfault described here: https://bugzilla.redhat.com/show_bug.cgi?id=1095986 Reproducible: Always
The linked bug references systemd-212, and the linked commit (2e9f08e) is present in systemd-213+. If you are getting a segfault in systemd-215, it is probably some other bug. Please build with debug symbols (-ggdb) and provide a full backtrace.
