I.e. it's not strictly POD according to the standard, but you can, e.g., memcpy it to a temporary area and then memcpy back. This is what we do with our JOINs sometimes. std::vector might lose state between memcpys. Or it can be something completely different -- in any case, it's hard to say without seeing the patch. --
