Thanks - great analysis!

However, I think there is a better fix for this - simply moving a }
one line. In particular, I'm concerned about passing the same pointer
both as input and output to the function - I couldn't find anything in
the documentation saying this was safe (nor did I find anything saying
it's unsafe, but.) Especially since this code clearly behaves
different on different versions - I've been completely unable to
reproduce this on any of my test machines, but they are all Windows
Server 2003.

So - attached is a new version of the patch, how does this look to
you? FYI, I've had Thom test this new version and it does appear to
work fine in his scenario.
