It appears to be used a lot in parsing arguments to functions (from a 
look at about 3 of the mentioned files).

My guess would be that it has something to do with the fact that you're 
running 2.1.46 while this was likly built with 2.1.71.  I think that ND 
arrays are new since then, and that would likely cause the problems.  Try 
upgrading your version of octave and see if it works again.
