Juts call configure with MSVS 2010 options.
64 bit should be default on 64 bit machine, isn’t it?

//and make sure you installed the patch (for VS2010) that corrects the memory corruption bug about 64bit O2 and structures bigger than 64bit.

Where I can get that patch, do you have link?

Here [support.microsoft.com] you can find information about bug and link to the patch is in that page too.

Thank you very much.

Also the recently launched SP1 [support.microsoft.com] for Visual Studio 2010 list some more fixed issues about x64 (issues with C++ compiler and optimizations)

So if I have already SP1 installed, the problem should be fixed?

I don’t know, they don’t specifically say that SP1 include that fix, but that fix is older than SP1 and usually the Microsoft service packs include all older updates and patches – so SP1 should include that too.

Ok, thank you very much.
