Hmm, if I try ncdump from either version 4.2.1.1 or the current snapshot, I get 
a different (but equally 
interesting) error:

  trunk$ ncdump -h 
http://testbedapps-dev.sura.org/thredds/dodsC/auto/in.usf.fvcom.ike.ultralite.vardrag.nowave.2d
nclistlength(connode->subnodes) <= nclistlength(fullnode->subnodes)

  ncdump: cdf3.c:482: mapnodes3r: Assertion 
`dappanic("nclistlength(connode->subnodes) <= 
nclistlength(fullnode->subnodes)")' failed.
  Abort(coredump)

Likewise, I verified that the 4.1.1 ncdump -h works fine here, too.

It looks like a bug.  I'm CC:ing Dennis in case he knows a fix for it ...
