radiusd crashing on FreeBSD 6.0

[Paul Khavkine]

Hi Guys.


I have radiusd 1.1.2 from the latest FreeBSD port crashing strangly
during a stress test.

I'm not sure where exactly it occurs because no core dump is produced.

Even when ran inside gdb, i can't get any backtrace info at all:

My system is FreeBSD 6.0-RELEASE-p2.
Core dumps are turned on in radiusd.conf, the system core file limit is
set to unlimited and i'm running the server as root.

It does crash when run with -x with a free() error:


 in free(): error: chunk is already free

Program terminated with signal SIGABRT, Aborted.
The program no longer exists.
(gdb) bt
No stack.
(gdb)

It does NOT crash when ran with -X

Does anyone have an idea how i can debug it further ?

Thanx
Paul
