--- Comment #12 from Franck Rousseau <Franck.Rousseau@imag.fr> ---
(In reply to Andrey V. Elsukov from comment #10)

Just to clear things up:
- the crash happens both in 11.2 and 12
- the proposed fix breaks ppp

I did more tests with ppp as explained in bug #227720 this morning and noti=
ced
the following:
- if the ppp server has two different addresses on the ethernet and ppp tun
interfaces, everything works fine, I can stop and start ppp without a probl=
em
- if I configure the same address on the ethernet interface as the one set =
up
on the tun interface, then the next ppp connection works fine, but if I stop
the server, restart and re-open from the client I consistently get a crash
