gdb backtrace would be helpful. But how to actually get it could be a
bit difficult, since I guess kernel thinks expire-tool is a setuid
program.

There are two ways I guess:

a) Apply attached diff1 and see if core dump gets written. Once you get
a core, use "gdb expire-tool core", "bt full".

b) If not, apply diff2 and start expire-tool. Then look up its pid and
run "gdb -p <pid>", "cont", wait for crash, "bt full".
