13006	serialization optional doesn't initialize stack_construct causes crashes	rob.vandennieuwenhof@…	Robert Ramey	"Boost\serialization\optional.hpp line 94

detail::stack_allocate<T> tp;

after some analysis we found that it should have been:
detail::stack_construct<Archive, T> tp(ar, item_version);

which then solves the crash"	Bugs	closed	Boost 1.65.0	serialization	Boost 1.64.0	Regression	fixed
