[PATCH 2/3] libstdc++: Optimize __uninitialized_default using memset

[Maciej Cencora]

Hi,

not sure whether I've missed some conditional that would exclude this case,
but your change seems to incorrectly handle trivial types that have a
non-zero bit pattern of value-initialized object, e.g. pointer to member.
