Aha, I don't have SP1 installed apparently (I remember I had some
problems with the installation of SP1, caused by general Windows
installation problems).

Now, I have pinpointed the exact revision where the problems start for
me. It's r1338286, where Bert enabled whole program optimizations for
release builds, in the vcnet_vcxproj.ezt file.

Maybe I'm running into some compiler bug (that has since been fixed in
SP1), related to whole program optimization. I'll try installing SP1
(but not right now, it's past 3 am now :-)) and see what happens.

Thanks for your help, Stefan.
