Nathan,

if I got you right, this happen's because I'm passing a reference to the
ostream object.
> ostream& func(ostream &stream, ...)

But, sorry, why in heavens sake this result's in undefined behaviour?
Is it really coincidence that it works like expected when gcc eventually
builds a binary? May it stall in, say 5 of 100, sucessive runs?

So, in short: I simply have to redesign my app to avoid this?
