Details:

Memory leaks when using nested functions.
Had to shut down and reboot windows when using larger array dimension. 
Control-C would not abort script execution.
See example below :

function memory_leak_driver()
  for k = 1:10000
    k
    f(  rand(4000) ) ;
  endfor
endfunction



The misbehaving function "f" is defined as:

  function retval = f( p )
    R = p*rand(1) ;
    f_blah  = @( ) 1./ R ;

    function retval = g()
      retval  = f_blah( ) ;
    endfunction

    retval  = g() ;

endfunction
