We shouldn't need these. In fact, they just hide bugs, and most
of them are superfluous anyways. The first hunk is a good find
though, I've integrated it in my patch.
Alexandre, please use this one instead.
ChangeLog
-- Fix outputing of a text pointer in debug mode (by Rein Klazes)
-- Remove a large bunch of superfluous ZeroMemory calls
-- Fix couple of bugs
