#2002: bugs in load_binary and save_binary on 64 bit machines

Milestone:  Boost 1.35.1                                 |   Component:  serialization
  Version:  Boost 1.35.0                                 |    Severity:  Regression   
 Keywords:  load_binary save_binary 64 bit               |  
---------------------------------------------------------+------------------
 I discovered that '''load_binary''' and '''save_binary''' do not work
 properly on 64 bit machines.[[BR]]
 I discovered the problem on CentOS 5.1, 32 and 64 bit machines, running
 the attached program with ''valgrind''.[[BR]]
 If you don't compile it with -DBOOST_SERIALIZATION_WORK_AROUND, the
 program runs correctly on the 32 bit machine only.[[BR]]
 On the 64 bit machine, the program seems to terminate correctly, but, if
 run with ''valgrind'', a lot of errors come out.[[BR]]
 This can appear as a minor bug, but, if you try to use Boost.MPI in
 conjunction with serialization (for example to broadcast an object of the
 class Mtx_Wrap ... see ticket #1998), your program crashes if you run it
 with more than one process.[[BR]]
 I have to add that, before boost 1.35.0 were released, I used the 1.35
 development version without any problem on 32 and 64 bit machines both. At
 the moment, I have a lot of code that uses  '''load_binary''' and
 '''save_binary''' like it is shown in the attached code.
