[Octave-bug-tracker] [bug #62459] Severe memory leak when functions are nested

[Rik]

Follow-up Comment #4, bug #62459 (project octave):

I also did some minor reworking of the test case which are attached as
memory_leak_script.m


for k = 0:10
  mem = memory();
  printf ("iter: %d, mem_used: %g\n", k, mem.mem_used_octave);
  fflush (stdout);
  leak_main_fcn (rand (4000));
endfor

printf ("------------------------------------------------------\n");
mem = memory();
printf ("iter: %d, mem_used: %g\n", k, mem.mem_used_octave);


and leak_main_fcn.m


function retval = leak_main_fcn (p)
  R = p*rand(1);
  leak_anon_fcn = @() 1./ R;

  function retval = leak_nested_fcn ()
    retval  = leak_anon_fcn () ;
  endfunction

  retval = leak_nested_fcn ();

endfunction


I also confirm increasing memory leakage with each function invocation and
that "clear all" does not remedy the situation.
