Hi there, I'm attempting to use a shared_array as member of a class that I have. Something akin to the following: class UTFStringHolder { ... boost::shared_array<unsigned short> mStrBufferP; }; When UTFStringHolder is instantiated, I get an EXC_BAD_ACCESS and my stack trace shows that pthread_mutex_init is being called. Here's the complete stack trace: #0 0x90012730 in _pthread_mutex_init #1 0x00088424 in boost::detail::lightweight_mutex::lightweight_mutex() at lwm_pthreads.hpp:47 #2 0x00088024 in boost::detail::lightweight_mutex::lightweight_mutex() at lwm_pthreads.hpp:49 #3 0x00087bc4 in boost::detail::sp_counted_base::sp_counted_base() at shared_count.hpp:98 #4 0x00086614 in boost::detail::sp_counted_base::sp_counted_base() at shared_count.hpp:99 #5 0x00098be0 in boost::detail::sp_counted_base_impl<unsigned short*, boost::checked_array_deleter<unsigned short>

Any ideas/pointers? I'm using boost v.1.32. Thanks for any help as I'm going bonkers. :-P Cheers, -C
