Hi, I get an error when I try to close the shared memory segment. My destructor calls simply mysegm.close(). I get the message below, but I can't interpret it so that I can do anything with it. It happens only if before a child process, that works in this segment too, is terminated erroneous and subsequently a faultless run was done. But to close the segment should be possible after errors too and at any time. When I restart my application without deleting the segment by hand it hangs in the constructor and I can wait forever, without any message. Thanks a lot, Sascha boost/shmem/detail/segment_manager.hpp:698: bool boost::shmem::detail::segment_manager<CharType, MemoryAlgorithm, IndexType>::priv_generic_named_destroy(const CharT*, typename boost::shmem::detail::segment_manager<CharType, MemoryAlgorithm, IndexType>::index_traits<CharT>::index_type&) [with T = std::pair<int, int>, CharT = char, CharType = char, MemoryAlgorithm = boost::shmem::simple_seq_fit<boost::shmem::shared_mutex_family, boost::shmem::offset_ptr<void, boost::shmem::offset_1_null_ptr> >, IndexType = boost::shmem::flat_map_index]: Assertion `0' failed.
