4256	boost::make_shared() may issue stack overflow while constructing large objects	faridz@…	Peter Dimov	"By default stack size for windows executable is 1Mb. The program below fails with stack overflow exception. In debug builds the stack overflow exception issued with A_Size >= ""stack size"" / 3. In release builds due to optimizations, the stack overflow exception issued with A_Size >= ""stack size"" / 2.

const std::size_t A_Size = 512;

struct A
{
    char buf_[A_Size * 1024];

int main()

    boost::shared_ptr<A> pa(boost::make_shared<A>());
    //boost::shared_ptr<A> pa(new A());
