Compiling angelscript x64 Debug in Visual Studio 2012 returns an error in as_gc.cpp on line 154:

1>..\..\source\as_gc.cpp(154): error C2220: warning treated as error - no 'object' file generated
1>..\..\source\as_gc.cpp(154): warning C4267: 'initializing' : conversion from 'size_t' to 'asUINT', possible loss of data

I managed to fix this by putting an explicit conversion to asUINT before gcNewObjects.GetLength();

Happy coding!
