[Boost-users] [Boost.Container] Performance of static_vector with default_init_t

Hi, I'm constructing a static_vector(n, default_init). I was expecting the constructor call to vanish into just setting the start pointer and the size & capacity members (and verifying n<=N). However, the profiler is showing some time spent in the loop inside uninitialized_default_init_alloc_n (boost/container/detail/utilities.hpp:678) For a builtin type and default_init_t, why do we even need to invoke the allocator? Can't we just leave the memory uninitialized? This is with Boost 1.55 and VS2008 Thanks in advance
