Parsing LLVM IR from bitcode file - c++

Question

I am trying to parse LLVM IR from a bit code file. I went through the following steps.
hello.cpp
#include <iostream>
int main() {
std::cout << "Hello world!" << "\n";
return 0;
}
dump.cpp
#include <llvm/IR/Module.h>
#include <llvm/IRReader/IRReader.h>
#include <llvm/IR/LLVMContext.h>
#include <llvm/Support/SourceMgr.h>
using namespace llvm;
int main()
{
LLVMContext context;
SMDiagnostic error;
Module *m = parseIRFile("hello.bc", error, context).get();
if(m)
{
m->dump();
}
return 0;
}
$ clang++ -O3 -emit-llvm hello.cpp -c -o hello.bc
$ clang++ -g -O3 dump.cpp llvm-config --cxxflags --ldflags --system-libs --libs all -o dump
$ ./dump
Assertion failed: (Val && "isa<> used on a null pointer"), function doit, file /Users/chamibuddhika/Builds/llvm/include/llvm/Support/Casting.h, line 106.
Abort trap: 6
So I get the above error at the end. What may be causing this? I am on llvm-6.0 rc2.
