Changing the compatibility setting for rustc.exe does nothing.
Running rustc.exe as admin does nothing.

Please let me know if you need any additional information. Also, if there is a debug build of stage0 I'd like to try it on my system.

I guess it caused by compatibility issue between your MinGW's libstdc++ version and what rustc.exe requires. rustc.exe in snapshot tarball doesn't works with libstdc++ 4.7.x and above.

If so, you should downgrade or just put 4.6.x's libstdc++-6.dll into i686-pc-mingw32/stage0/bin/stage0.

Currently we only support 32-bit Windows. Given that it's been four months, I'm going to close this for now. Try again on the same machine once 0.7 is released and reopen if this still happens (and ensure you have the right MinGW version).
