Hi All, I am facing a core dump while serializing adjacency_list class object of BGL. I am using <boost/graph/adj_list_serialize.hpp> file for serialization. Following is the stack trace. I have highlighted the types used for boost::adjacency_list on frame number 19. I am using bundled property method to assign property to nodes and vertices. I tried with no_poperty, the outcome was the same. Does anyone have any idea, why is it crashing? The exception name is "output stream error". #0 0x0000003908e359e9 in raise () from /lib64/libc.so.6 #1 0x0000003908e370f8 in abort () from /lib64/libc.so.6 #2 0x000000390d660565 in __gnu_cxx::__verbose_terminate_handler() () from /lib64/libstdc++.so.6 #3 0x000000390d65e6c6 in ??
