---------------------------------------------------------+------------------
 I have a simple program that performs an '''mpi::broadcast''' of an object
 of a user-defined class.[[BR]]
 While the program runs with no error on a CentOS 5.1, 32 bit, machine, it
 crashes on a CentOS 5.1, 64 bit machine (segmentation fault). The MPI
 implementation I use it's mpich2-1.0.6p1.[[BR]]
 It seems there's some problem with the packed_iarchive (I checked with
 valgrind). I cannot find any error in my code (it's nearly 3 days that I'm
 trying to find if there is an error in my code, but I don't see any
 error).[[BR]]
 The program attached crashes with more than one process. It does not crash
 if you activate the second dataset (uncomment lines 153-154 and comment
 lines 150-151).[[BR]]
 I'm using Boost 1.35.0, checked out from the svn repository.
