Here are a couple of questions which will help me reproduce:

* What is your version of sydbox? (if -scm, git commit ID please.)
* What options have you compiled sydbox with? (especially interested in
[seccomp])
* What architecture?
* What is the exact permissions of this file? (ls -la /tmp/test-setgid.*)
* Is your user a member of the group which this file belongs to?

This is it for now.

(Note to self: 23 == AT_SECURE defined in <elf.h>)
