--------------------------------------------+-------------------------------
 It appears that text_oarchive::save_binary() reads one byte too many. In
 other words, save_binary(addr,len) appears to read byte addr+len. The
 attached program, which runs on Linux, allocates a page of zeroes with
 mmap(2) and then serializes the last few bytes of the page with
 text_oarchive::save_binary(). The result is a segmentation fault.
