Faild to compile my project on W7 64 and OS hung up

[poiuyt555]

Hi.
I have project that was succsessfuly build in 32-bit OS and lazarus 1.0.10 fpc2.6.2.

Now i try to compile it on another PC:
Windows 7 64-bit.
Lazarus-1.1-41859-fpc-2.6.2-20130624-win64.exe

And i faild to compile.
When Copiling in messages windows i saw the hints ... Variable doesn't seem to be initialize (and etc.)... and that is all
My Windows is hung up on this moment. i was waiting for 30 minutes, and nothing not happend..

The only way is - reboot system by pressing the reboot button on PC.

Why it is so, what is the problem?

Note: i have some test project that works and compiles successfully both 32 and 64 pc's and Lazarus.
I can't compile only one project.

See anything weird in the task manager?

Thanks, Task manager is not available, only physical reboot are available....
Now i have deleted those unstable releases, and successfully compiled with the official stable release:
lazarus-1.0.10-fpc-2.6.2-win64.exe
