I looked over the CVS version and it doesn't appear to have the changes I
thought it would.

The offending line of code is

   return (ifp->flags & (IFF_LOOPBACK|IFF_NOXMIT|IFF_VIRTUAL));

in the if_is_loopback() function in lib/if.c.  Obviously, ifp->flags must have
an invalid value.  I still don't see any error-checking in this function or in
the function that's calling it (ospf_if_is_enable() in ospfd/ospf_interface.c)
in the CVS version.  What exactly was changed to fix this if it wasn't
error-checking?

Well, ifp is NULL:

#0  0x28113f86 in if_is_loopback (ifp=0x0) at if.c:367

which shouldn't happen, oi->ifp should always be valid. This is likely fixed in
0.99.5+ - please test that.
