Hello,
recently our radius died again. It's taken from CVS short before 0.5.
A moment before the crash the server has got a -HUP to reload it's config.
Reading the below backtrace, I suspect, there was still a task accessing
the old, already free()ed config.
I suppose, this isn't easy to fix. Since the crash happened only once,
it's not important to me to get a fix soon.
