Description Thorsten Behrens (allotropia) 2019-12-20 14:44:07 UTC 
Open more than one document from the same WebDAV server. Set session timeout to something small enough, wait for timeout to hit.

First document will then invalidate session in ah_post_send, second document crash while accessing nullptr below auth_challenge().

The code is windows-only, change came into neon library via:
