[OLSR-users] interaction between mobile ipv6 and olsr

[Andreas Tønnesen]

We would really like to have this issue fixed in 0.4.10. If the
core dump is too much trouble a gdb backtrace would also be
of help.
Here are some easy steps:

gdb olsrd
run

Now when olsrd crashes do
bt

and post the output of the entire session on the list. Also the
configuration file would be useful. If you could use the current
CVS version that would be even better!
This would be really helpfull :-) If others have seen the same
issue, feel free to reply to this.
