Wormholes may have this problem, the jury is still out on that. The
energy densities and space-time curvatures involved in wormholes are
comparable to black holes (but "negative" in some sense), and there
are many wormhole models that are not traversable at all since they
collapse, have infinite blueshifts and other nastiness. But on the
other hand, just as very large black holes would have fairly weak
tidal forces at their event horizons, traversable wormholes with
sufficiently large throats might be survivable.
