--------
Bug report for Octave 2.0.11 configured for alphaev56-dec-osf4.0b

Description:
-----------

I am observing a memory leak when I run the following simple script:

% mem_leak.m
%
% watch this process grow and grow using "ps -l"
%
% JM 5/18/98

for n =  1:10000000
  m=myfunc(1);
end


% myfunc.m
%
% called by mem_leak.m to demo bug
%
% JM 5/18/98

function m=myfunc(n);
m=n+1;


Repeat-By:
---------

The memory leak was observed anytime a function call was included. I
obtained octave as a binary from one of the "official sites"
