What are the values of x and t here?  X should be a 3-element vector
and t shoould be some vector of positive real numbers with increasing
values.  Since there is no error checking in the oregonator function,
it can crash Octave if you give it bogus parameters.

Are you sure you were calling lsode without any arguments?  When I do
that, I get the lsode help message.  Could it have been that you
actually called oregonator without arguments?
