I am creating a multi-index on three members of a class (two int32_t and one std::pair and storing that in a managed memory mapped file (boos::interprocess). I am using GCC 4.8.2 for compilation and boost version 1.56.beta1All the data is first inserted into the multi-index once and then it is read from the muti-index with a query on the first two int32_t values (There is no concurrency and insertion and query is being done within the same process). The mutliindex is defined as:
typedef bmi::multi_index_container < Trace, bmi::indexed_by < bmi::ordered_non_unique < bmi::composite_key < Trace, BOOST_MULTI_INDEX_MEMBER(Trace, int32_t, m_x), BOOST_MULTI_INDEX_MEMBER(Trace, int32_t, m_y), BOOST_MULTI_INDEX_MEMBER(Trace, int_pair_t, m_volume) > > > , managed_mapped_file::allocator<Trace>::type > trace_set_t;
The query is:
boost::tie(l, u) = m_p_mi_ts->get<0>().equal_range(boost::make_tuple(i, j));
We are testing this whole process over and over again (each iteration is a new run of the process), and once in every 50 or so iterations we get a segment fault inside boost on firing the query. Here is the boost part of the stack from the core dump:

Any idea what might be happening?
