Hmm, interesting!  Ok, next step:

1. Build again with `make CFLAGS="-O0 -g"`.
2. Run the utility and watch it crash.
3. Run `gdb ./spiped/spiped spiped.core` and at the prompt "p key" and
"p rkeys".

If gdb complains that spiped.core doesn't exist you'll need to enable
core dumps -- I'm not sure if Ubuntu has them turned on by default.

I *think* I know what the problem is here, but seeing the value of those
two pointers when the crash occurs should confirm it.
