Hello, I'm working on a parallel physical simulation involving particles in a 3D grid. In addition to Boost libraries, I use the Eigen3 template library for holding numerical data in small 3-vectors. I'm trying to send a 3D boost::multi_array containing std::list of pointers to particle structs via boost::mpi and keep getting a segfault on receive. Sending and receiving boost::multi_array of V3D Eigen3 vectors works fine. Serialization functions for multi_array are from http://tinyurl.com/3koafmr (edited for 3 dimensions, seems to work) Serializing Eigen Vector3d type (seems to work): friend class boost::serialization::access; template<class Archive> inline void serialize(Archive & ar, const unsigned int file_version) { ar & m_coeffs.x(); ar & m_coeffs.y(); ar & m_coeffs.z(); } typedef Vector3d V3D; //Convenience typedef for Eigen3 vector struct Particle { V3D r, u; double m, q; unsigned number; friend class boost::serialization::access; template<class Archive> void serialize(Archive & ar, const unsigned int file_version) { ar & r; ar & u; ar & m; ar & q; ar & number; } }; Sending point: typedef boost::multi_array<std::list<Particle*>, 3> ParticleArray; ParticleArray part_array(boost::extents[x][y][z]); ...fill the array with particles, some cells might be empty... world->isend(recnum, pack_type, part_array); Receiving point: ParticleArray part_array(boost::extents[slice->shape()[0]][slice->shape()[1]][slice->shape()[2]]); world->recv(sendnum, pack_type, part_array); When I get here, it segfaults: terminate called after throwing an instance of 'boost::archive::archive_exception' what(): class version # 0 0 Program received signal SIGABRT, Aborted. 0x00007ffff5a29a25 in raise () from /lib64/libc.so.6 (gdb) bt #0 0x00007ffff5a29a25 in raise () from /lib64/libc.so.6 #1 0x00007ffff5a2b0af in abort () from /lib64/libc.so.6 #2 0x00007ffff64fb695 in __gnu_cxx::__verbose_terminate_handler () at /var/tmp/portage/sys-devel/gcc-4.4.5/work/gcc-4.4.5/libstdc++-v3/libsupc++/vterminate.cc:93 #3 0x00007ffff64f9ac6 in __cxxabiv1::__terminate (handler=0x70d) at /var/tmp/portage/sys-devel/gcc-4.4.5/work/gcc-4.4.5/libstdc++-v3/libsupc++/eh_terminate.cc:38 #4 0x00007ffff64f9af3 in std::terminate () at /var/tmp/portage/sys-devel/gcc-4.4.5/work/gcc-4.4.5/libstdc++-v3/libsupc++/eh_terminate.cc:48 #5 0x00007ffff64f9bee in __cxxabiv1::__cxa_throw (obj=<value optimized out>, tinfo=<value optimized out>, dest=<value optimized out>) at /var/tmp/portage/sys-devel/gcc-4.4.5/work/gcc-4.4.5/libstdc++-v3/libsupc++/eh_throw.cc:83 #6 0x000000000044f7d5 in boost::archive::detail::iserializer<boost::mpi::packed_iarchive, Particle>::load_object_data(boost::archive::detail::basic_iarchive&, void*, unsigned int) const () #7 0x00007ffff794173b in load_object (this=0x7fffffffcae0, t=<value optimized out>, bis=...) at libs/serialization/src/basic_iarchive.cpp:367 #8 boost::archive::detail::basic_iarchive::load_object (this=0x7fffffffcae0, t=<value optimized out>, bis=...) at libs/serialization/src/basic_iarchive.cpp:547 #9 0x000000000044f662 in boost::archive::detail::pointer_iserializer<boost::mpi::packed_iarchive, Particle>::load_object_ptr(boost::archive::detail::basic_iarchive&, void*&, unsigned int) const () #10 0x00007ffff7941c50 in load_pointer (this=0x7fffffffcae0, t=@0x7fffffffc880, bpis_ptr=0x668060, finder=<value optimized out>) at libs/serialization/src/basic_iarchive.cpp:494 #11 boost::archive::detail::basic_iarchive::load_pointer (this=0x7fffffffcae0, t=@0x7fffffffc880, bpis_ptr=0x668060, finder=<value optimized out>) at libs/serialization/src/basic_iarchive.cpp:560 #12 0x000000000044ed6f in boost::archive::detail::iserializer<boost::mpi::packed_iarchive, std::list<Particle*, std::allocator<Particle*> >

Again, this error only shows when receiving the multi_array of std::list<Particle*>. multi_array of V3D is received fine. Thanks for any help, Jiri Vyskocil
