Yes. I ran into this about four weeks ago. It is a nontrivial bug in
the handling of terminal links. It is, however, sensitive to changes in
the input.

Here is a minimal map I came up with. Note the different behaviour
when you swap the two lines for agsc.

pathalias -c -l agsc <<!END!
agsc	metropo
agsc	influx

influx	<climax>
climax	<metropo>
metropo	<influx>
!END!

Apparently all versions of pathalias have this problem. The Smail3
version produces negative costs in this case. The version on
citi.umich.edu just eats up all memory producing no output. And the
version on uunet produces recursive paths too, I am told.

The smail3 version should not only produce recursive paths for the above
input, it should get the wrong host before the last bang. :-(

If you need a preliminary fix, mail me.
