There is an easy fix for this, attached.
Patch applied; no core dump in 24 hours.
This appears to have fixed the problem. I found that it crashed when
the policy server responded too quickly. As the before and after auth
command=allow request are the same I cache the first, leading to a fast
second response. Removing the cache (nginx proxy_cache ...) must change
the timings and circumvented the crash. Why use both check before and
after auth? roundcube webmail reports an error with only
auth_policy_check_before_auth. I cannot see why. The simple and lazy
solution is to use double auth_policy_check_!
Thank you Aki for looking at this and finding a solution so quickly.
