Why are you allocating memory and immediately dropping track of it?
Recheck how ID3DXMesh::LockVertexBuffer works.
Also I'm having a deja-vu here, this patch looks suspiciously similar
(up to having this same issue) to one I've already reviewed in the
past.

It is a leftover of my tests about the requested size of the buffer :( ....

Also I'm having a deja-vu here, this patch looks suspiciously similar

I don't understand what you mean here. Can you tell more?

I send a newer version. This one should be fine.
