Sample code:


try
  z = zeros (2^53,1);
catch ME
  disp ('in catch block');
  rethrow (ME);
end


When run in Octave it produces the output:


error: out of memory or dimension too large for Octave's index type
error: called from
    tst_rethrow_ordering at line 2 column 5
in catch block


In Matlab, the code in the catch block that precedes the rethrow () call is
executed first and printed first.  This seems more logical as execution is
from top to bottom.

One can resolve this by adding "fflush (stdout)" before the call to rethrow(),
but it would probably be better to have rethrow do the flushing.
