I can't answer for who wrote the code, but I don't consider this a bug 
myself. I don't think that Octave itself failed as much as the 
evaluation failed (the reasons are clearly presented, too). This seems 
to me a successful attempt to evaluate an expression, even though this 
resolves into errors.

I don't think it would be an issue to return a nonzero value in this 
case, but I also don't think it would fix anything.
