Executable generated with clang++ goes crazy

#include<iostream>
#include<cstdlib>
#include<cstring>
#include<cstdio>
using namespace std;

id Book{
public:
int a;
int b;
};

int main()
{
Book b1;
b1.a = 10;
b1.b = 20;
cout<< b1.a << ' ' <<b1.b;
}


when we compile the above code with

clang++ test.cc -o a.exe


and run a.exe works perfectly. But when we compile the same program with

clang++ test.cc -emit-llvm -S -o a.exe


and now when we run it, the program goes crazy by launching ntvdm.exe (can be seen in process explorer) and command prompt starts behaving weird.

Software stack:

clang version 2.9 (tags/RELEASE_29/final)
Target: i386-pc-mingw32
Thread model: posix
