[pptp-server] Crash PPTP

[pptp at alpha.szczepanek.de]

Hi!

I am trying to use pptp server 1.0.0 under Suse Linux 7.0 using Kernel
2.2.16 with SMP support for a big network (student hostels bonn).

Today we ran some tests and the pptpd stopped. This is what I got from the
kernel log:

Is this a problem of pptpd 1.0.0? Should I use a development version? Is
this a known bug?!?
