Axel Dörfler 815c38625d Applied patch by Vasilis Kaoutsis:
* replaced new[] with malloc()/realloc() where appropriate - since we're messing with
  the bits anyway, this makes the code slightly faster.
* however, we might want to throw some std::bad_alloc exceptions to deal correctly with
  low memory situations.
* cleanup.
