Segment fault for C++ program when return vector

I am trying to reverse complement DNA sequence (string) with a short c++ code using boost library. Code was compiled without any warning/error, but ran into Segmentation fault.
My guess is the function to return a vector, but not sure.

Code:

#include <iostream>
#include <fstream>
#include <string>
#include <vector>
#include <boost/assign.hpp>

using namespace std;
using namespace boost::assign;

vector <char> revcomp(string str) 
{
vector <char> str_rc;
map <char, char> m = map_list_of('A','T')('T','A')('G','C')('C','G');

for (unsigned i = str.size(); i >= 0 ; --i)
{
str_rc.push_back(m[str[i]]);        //get all the chars except str[0]
}
str_rc.push_back(m[str[0]]);        //get the first char 

return str_rc;
}

int main()
{
vector <char> str2;
string str1 = "ATCGTTTCCC";
str2 = revcomp(str1);

vector<char>::iterator itr2;
for (itr2 = str2.begin(); itr2 != str2.end(); ++itr2)
{
cout << *itr2;
}
cout << endl;

return 0;
}

Code:

$ g++ -Wall revcomp.cpp 
$ ./a.out
Segmentation fault

Can anyone look into it? Thanks a lot!

Pod::WSDL::Fault(3pm)					User Contributed Perl Documentation				     Pod::WSDL::Fault(3pm)

NAME

       Pod::WSDL::Fault - Represents the WSDL pod describing the fault of a method (internal use only)

SYNOPSIS

	 use Pod::WSDL::Fault;
	 my $fault = new Pod::WSDL::Fault('_FAULT My::Fault This happens if something happens');

DESCRIPTION

       This module is used internally by Pod::WSDL. It is unlikely that you have to interact directly with it. If that is the case, take a look at
       the code, it is rather simple.

METHODS

   new
       Instantiates a new Pod::WSDL::Fault. The method needs one parameter, the fault string from the pod. Please see SYNOPSIS or the section "Pod
       Syntax" in the description of Pod::WSDL.
