[Olsr-users] Segmentation_fault:n

[Henning Rogge]

Hmm...

I don't see any mesh interfaces defined... did you cut out a part of your
configuration or did you set them with command line options?

This looks like a pure DLEP router receiver configuration without any
OLSRd2 component... but you get a segfault in NHDP.
