freeradius 3.0.15 memory corruption

[petr.linke at seznam.cz]

Only additional info. The same situation is with winbind method - username 
without domain with length more than 5 characters = memory corruption. 
Username (length > 5 char) with domain = OK.

Subject: Re: freeradius 3.0.15 memory corruption 
When I fill into username only name without domain, the memory corruption 
appears. When I put into username DOMAIN\NAME, all works fine.
In the module mschap I have set the default domain in ntlm_auth command via 
--domain=%{%{mschap:NT-Domain}:-TEST.LOCAL}, so during the tests I do not 
fill the domain into username.

Which doesn't show the packet coming in, or what you're doing to it. Having 
*some* information would be useful.

Please follow doc/bugs to get a useful backtrace.

Or. run it in debugging mode with "radiusd -Xxx". You'll get a LOT more 
output, and the server will do additional memory sanity checking. That may 
show something useful.
