segfault at the end of the main() - c++

Question

I am compiling a program agains LLVM-CLANG. This is the main
#include <iostream>
#include "CompilerFactory.h"
#include "clang/Basic/FileManager.h"
#include "clang/Basic/SourceManager.h"
#include "clang/Lex/Preprocessor.h"
#include "clang/Basic/Diagnostic.h"
int main(int argc, char const *argv[])
{
using clang::CompilerInstance;
using clang::TargetOptions;
using clang::TargetInfo;
using clang::FileEntry;
using clang::Token;
using clang::DiagnosticOptions;
using clang::TextDiagnosticPrinter;
CompilerInstance ci;
CSFV::CompilerFactory::GetCompilerInstance(ci);
const FileEntry *pFile = ci.getFileManager().getFile("test.c");
ci.getSourceManager().createMainFileID(pFile);
ci.getPreprocessor().EnterMainSourceFile();
ci.getDiagnosticClient().BeginSourceFile(ci.getLangOpts(),
&ci.getPreprocessor());
Token tok;
do
{
ci.getPreprocessor().Lex(tok);
if (ci.getDiagnostics().hasErrorOccurred())
break;
ci.getPreprocessor().DumpToken(tok);
std::cerr << std::endl;
} while (tok.isNot(clang::tok::eof));
ci.getDiagnosticClient().EndSourceFile();
return 0;
}
and this is the included class
//If they are not defined we have an error at compile time
#define __STDC_LIMIT_MACROS
#define __STDC_CONSTANT_MACROS
#include "llvm/Support/Host.h"
#include "llvm/ADT/IntrusiveRefCntPtr.h"
#include "clang/Basic/DiagnosticOptions.h"
#include "clang/Frontend/TextDiagnosticPrinter.h"
#include "clang/Frontend/CompilerInstance.h"
#include "clang/Basic/TargetOptions.h"
#include "clang/Basic/TargetInfo.h"
using namespace clang;
namespace CSFV{
class CompilerFactory
{
public:
CompilerFactory();
~CompilerFactory();
/// \brief Generate and returns a compiler instance object
static void GetCompilerInstance(CompilerInstance &ci){
DiagnosticOptions diagOpts;
TextDiagnosticPrinter* diagPrinter =
new TextDiagnosticPrinter(llvm::outs(), &diagOpts, true);
ci.createDiagnostics(diagPrinter);
llvm::IntrusiveRefCntPtr<TargetOptions> pto (new TargetOptions());
pto->Triple = llvm::sys::getDefaultTargetTriple();
TargetInfo *pti =
TargetInfo::CreateTargetInfo(ci.getDiagnostics(), pto.getPtr());
ci.setTarget(pti);
ci.createFileManager();
ci.createSourceManager(ci.getFileManager());
ci.createPreprocessor();
return;
}
};
} //end of namespace CSFV
For some reason I get a segfault at the end of the execution of the main. What am I missing?

I don't know if this is the same problem I had, but what I did was declare the targetoptions as a new pointer.
eg:
clang::TargetOptions *targetOpts=new clang::TargetOptions;
I have a feeling targetinfo cleans it up when itself is destroyed.
