source code
revision 16146. Run sac2c -b11:cyc. Look at function 
ArrayTransform::_dup_1167_rotate__Cond_48
It starts in line 7879.
Then we have declarations
 {
  int _esd_12471 {  } ;
  int _esd_12470 {  } ;
  int _esd_12469 {  } ;
  int _esd_12468 {  } ;
  int _esd_12467 {  } ;
  int _esd_12466 {  } ;
  int _esd_12465 {  } ;
  int _esd_12464 {  } ;
....
 until line 11460(!)
followed by "normal declarations.
A bit later (line 11641) we find
            _esd_12471 = _sub_SxS_( 0, _cf_2755_iv);
            _esd_7735 = _sub_SxS_( 0, _cf_2755_iv);
            _esd_12470 = _sub_SxS_( 0, _cf_2755_iv);
            _esd_5367 = _sub_SxS_( 0, _cf_2755_iv);
            _esd_12469 = _sub_SxS_( 0, _cf_2755_iv);
            _esd_7734 = _sub_SxS_( 0, _cf_2755_iv);
            _esd_12468 = _sub_SxS_( 0, _cf_2755_iv);
            _esd_4183 = _sub_SxS_( 0, _cf_2755_iv);
....
  until line 14781(!!!!)
we see further situations of similar code explosions further down.
I believe to remember that there was a known issue with esd and I assume it
might only be a matter of running the right sequence (eg CSE should do)
BUT I think that such an explosion needs to be controlled!!!
