Preprocessed source and run script

The following invalid template code crashed the clang compiler:

template <class T1>
class SomeClass
{
public:
    template <class T2>
    void SomeFunc(T2 someArg)
    {}
};

template <class T1>
void SomeClass<T1>::SomeFunc<int>(int someArg)
{}


The development environment is Windows 8.1 with Visual Studio 2013 Update 3,
using the following distribution of Clang for Windows:
