Can memdbg builds be enhanced in a way that makes sure the returned
address matches the required alignment, but not a higher alignment?
For that purpose, memdbg would need to allocate somewhat more memory,
and return an appropriate pointer.
That way, these bugs woudn't be intermittent anymore (at least for
memdbg builds).
