Subject: v2 memory crazyness

Hey guys,
this really looks like a big bug somewhere: compile the following code and
you'll se how v2 eats memory. Nope, it is not a malloc trouble: you can
obtain the same using new/delete.
What's worse the memory get lost only when referenced: strip out the zepo
padding code and no more trouble with that...
Hey guys: this think drove me crazy (you know what you mean: hey, I was sure
I freed all the pointers... ;).
Of course it could even be a cwsdpmi trouble...

Ciao,
	Davide.

PS: It's quite a lot I don't receive any message: who the hell kicked me off
the list? Should I re-subscribe?
