Not sure whos fault is this

Guys, the code below causes msg with info that SIGSEGV occured etc. The point is that the same code compiles fine with the same compiler but with different IDE (Qt),so I thought I let you know that when code::blocks is used something is going pairshaped :
#include <iostream>
#include <string>
#include <algorithm>
using std::cout;



std::string encode(const std::string& decoded)
{
   std::string encoded_url(decoded);//SIGSEGV_E this line causes signal SIGSEGV
   typedef typename std::string::iterator iterator;
   for (iterator i = encoded_url.begin();(i = std::find(i,encoded_url.end(),'%')) != encoded_url.end();++i)        {
       cout << *i << *(i + 1) << *(i + 2) << '\n';
   }
   return encoded_url;
}
int main()
{
   std::string decoded_url("http%3A%2F%2Fo-o---preferred---sn-xn5ucu-q0ce---v20---lscache7.c.youtube.com%2Fvideoplayback%3Fupn%3DQfNLYnp9JHM%26sparams%3Dcp%252Cgcr%252Cid%252Cip%252Cipbits%252Citag%252Cratebypass%252Csource%252Cupn%252Cexpire%26fexp%3D907724%252C923009%252C914070%252C916626%252C922401%252C920704%252C912806%252C927201%252C925703%252C925706%252C928001%252C922403%252C913546%252C913556%252C920201%252C911116%252C901451%26ms%3Dau%26expire%3D1354491207%26itag%3D43%26ipbits%3D8%26gcr%3Die%26sver%3D3%26ratebypass%3Dyes%26mt%3D1354467611%26ip%3D89.204.226.98%26mv%3Dm%26source%3Dyoutube%26key%3Dyt1%26cp%3DU0hUSVRUT19FUUNONF9MTlNDOm05Ql9HWWNIejNM%26id%3Dcaf9021d49b11ad9%26newshard%3Dyes&type=video%2Fwebm%3B+codecs%3D%22vp8.0%2C+vorbis%22&fallback_host=tc.v1.cache5.c.youtube.com&sig=63E945F5FCC5744AFDA6A473D2B7D3A464DC56AE.31AF09E39FFF100E5A5066418689DA3DD4D78C37&quality=medium");
   cout << encode(decoded_url);
   return 0;
}

Edit: You need to verify the compiler and linker commands match or at least closely match.
