I'm honestly not sure. To be safe i've changed the code... It wasn't wrong, but it's the sort of thing that might break between talloc versions.

Anyway, the SEGV is secondary, the issue here is bad parenting of the VALUE_PAIR. Could you use latest head and try again?

If you run it in with:
PANIC_ACTION="gdb %e %p" radiusd -lstdout -f

It'll dump you into an interactive GDB prompt, and you can poke around a bit.
