It looks like I was able to fix a bug which makes it run correctly under MSVC 2015 Express. Although I do have a crash in the boost::pool: Project2.exe!boost::simple_segregated_storage<unsigned int>::try_malloc_n(void * & start, unsigned int n, unsigned int partition_size) Line 333 C++ Project2.exe!boost::simple_segregated_storage<unsigned int>::malloc_n(unsigned int n, unsigned int partition_size) Line 363 C++ Project2.exe!boost::poolboost::default_user_allocator_new_delete::ordered_malloc(unsigned int n) Line 801 C++ Project2.exe!boost::singleton_poolboost::detail::bp::pool,1,boost::default_user_allocator_new_delete,boost::de...::ordered_malloc(const unsigned int n) Line 149 C++ Project2.exe!boost::detail::bp::pool::allocate(unsigned int s) Line 148 C++ Project2.exe!boost::detail::bp::block<int>::operator new(unsigned int s) Line 283 C++ Project2.exe!boost::detail::bp::make_block(const int & t0) Line 520 C++

When I try this example: https://github.com/philippeb8/block_ptr/blob/master/example/block_ptr_test2.... Thanks, -Phil
