I meant something like this:

     /* The while loop below was originally this:

        while ((unsigned int) (info_ptr - dwarf_info_buffer)
              ((info_ptr - dwarf_info_buffer) % 4) < dwarf_info_size)

        This seems to be trying to round info_ptr up to the next 
        four-byte boundary, but that's not what it actually did.  If we 
        discover the problem the old code was really trying to address, 
        we can fix it properly.  */
