Qt 4.7 64bit msvc2010 Tools crash

Hi.
I've just built a 64 bit version of a Qt 4.7 snapshot (downloaded from the repository) using Microsoft Visual Studio 2010.

I haven't had compilation errors, but the tools in the bin/ folder won't start.

For example I'm not able to use designer.exe because it crashes during startup (access violation: segmentation fault).

I've tried to build a simple "Hello world" program and it works.

Do you have some ideas?

Thanks

Can it be a problem of 64 bit's architecture, or maybe a msvc2010 compatibility problem?

Some demos and examples work fine (qt browser, affine transformations...), others crash during start up or when using their features.

It seems I'll have to wait a more stable Qt release

This is due to a bug in the MSVC 2010 compiler (64 bit): http://bugreports.qt.nokia.com/browse/QTBUG-11445

Wow, that's... wow.

One hopes that the Microsoft employee who answered isn't actually a developer for them. The (former or present) MS developers I've known have all been sharp folks. Of course, if they just allocated *everything* on the heap, it would explain a few things about Windows... :-D
