I just noticed this in the debug messages:

I still have no clue what the heck is going on though…
Hum, incidentally GtkScrolledWindow contains bitfields, would it be possible it is a -mms-bitfields-like problem? We really seem to pass -mms-bitfields, but maybe gtkscrolledwindow.c wasn't build with it or something like that?
Wow, great process, Colomban. Reading your previous mail the -mms-bitfields thingy instantly came also to my mind.
I checked the nightly builds as well the builds on my Windows VM, both had -mms-bitfields set, also for PlatGTK.cxx. This opton is set by gtk+-2.0.pc (GTK pkgconfig file), so it's obvious both builds have it set.
But maybe it's related to the compiler version. The cross-compiled nightlies are a bit special in terms of cross-compiling and that they use a quite old mingw-gcc 3.4 while the mingw-gcc on my Windows VM is a more recent 4.8. I found http://gcc.gnu.org/gcc-4.7/changes.html where a short note says: Windows mingw targets are using the -mms-bitfields option by default.
I would say this is probably not relevant because we compile our code with -mms-bitfields in all cases because GTK pulls it in. But IANAC (I am not a compiler :D).
Does anyone here has by accident a Windows system with a mingw-gcc < 4.7?
I'll try to further debug this on the weekend if I find time.
