Backtrace of ldap related crash

[Franks Andy (IT Technical Architecture Manager)]

Hi all,
  FreeRADIUS Version 3.1.0 (git #390f216), built from source (just testing!)

I'm getting the below when having timeouts and connectivity issues with our ldap servers, normally it's fine, but it's still a crash..
Can anybody tell if this issue is fixed and we should upgrade?
Ideally we'd have ldap go completely wrong but freeradius ride on through it.
Thanks
Andy
