We incorrectly compute MPI_Offset for MPI IO for checkpointing using SolutionTransfer using 32 bit indices, which means that files larger than 4GB end up being corrupted. This manifests in errors like n error occurred in line <749> of file <../source/distributed/tria_base.cc> in function void dealii::parallel::DistributedTriangulationBase<dim, spacedim>::load_attached_data(unsigned int, unsigned int, unsigned int, const string&, unsigned int, unsigned int) [with int dim = 3; int spacedim = 3; std::string = std::__cxx11::basic_string<char>] The violated condition was: (cell_rel.second == parallel::DistributedTriangulationBase<dim, spacedim>::CELL_PERSIST) part of dealii#12752
