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."
