Hello, following the bug report this morning, I upgraded to the SVN version [7274]. Unfortunately, I can not longer save boost::multi_array in the load / save functions. The compile error I get is […]/alps/include/alps/osiris/dump.h: In function 'alps::IDump& alps::operator>>(alps::IDump&, T&) [with T = boost::multi_array<double, 3u, std::allocator<double> >]': […]/alps/include/alps/osiris/dump.h:242:37: error: 'class boost::multi_array<double, 3u, std::allocator<double> >' has no member named 'load' I know that in principal I have to take care of serialising objects but at least in [6172] this worked fine. Can I fix this easily? Best, Peter
