Details:

Repeated .oct file calls causes octave process to accumulate memory and
(eventually) crash, on both a Dell M4400 Win7 using v3.2 sourceforge binary
and Toshiba Satellite Ubuntu 10/v3.4.2 compiled from source. 



string = [ ...
  "\n" '#include <octave/oct.h>' ...
  "\n" 'DEFUN_DLD (helloworld, args, nargout, "Hello World Help String")' ...
  "\n" '{' ...
  "\n\t" 'int nargin = args.length ();' ...
  "\n\t" 'octave_stdout << "Hello World has " << nargin' ...
  "\n\t" '   << " input arguments and "' ...
  "\n\t" '<< nargout << " output arguments.\n";' ...
  "\n\t" 'return octave_value_list ();' ...
  "\n" '}' ...
  "\n"
  ];

fid = fopen('helloworld.cc', 'w');
fputs(fid, string);
fclose(fid);

mkoctfile helloworld.cc

for (i=1:1000000000)  % set = 1 billion --> crash
  helloworld;
end
