--- Comment #4 from Jürgen Reuter <juergen.reuter at desy dot de> ---
This is the dump-tree-original file, which is produced despite of the ICE, and
which is identical for -O1 and -O2:

;; Function __sputc (null)
;; enabled by -tree-original


{
  if ( --_p->_w >= 0 || _p->_w >= _p->_lbfsize && (signed char) _c != 10)
    {
      return (int) (*_p->_p++  = (unsigned char) _c);
    }
  else
    {
      return __swbuf (_c, _p);
    }
}


;; Function hoo (null)
;; enabled by -tree-original


{
  int slen;
  char file[32];

    int slen;
    char file[32];
  __builtin___strcpy_chk ((char *) &file, (const char *) in,
__builtin_object_size ((const void *) &file, 1));
  slen = (int) strlen ((const char *) &file);
  __builtin___sprintf_chk ((char *) &file + (sizetype) slen, 0,
__builtin_object_size ((const void *) &file + (sizetype) slen, 1), (const char
*) "1.out");
}
