Botan c++ hash function generate_bcrypt()

Question

I am trying to get hash of password using Botan's function generate_bcrypt().
I read manual http://botan.randombit.net/passhash.html here. Afterwards I have read it yet once. Source code:

#include <botan/botan.h>
#include <botan-1.10/botan/bcrypt.h>
#include <stdio.h>
#include <iostream>

 using namespace Botan;

 int main(int argc, char *argv[])
 {
   LibraryInitializer init;

   std::string passw="12dnblkndlnbfndlknblf";
   AutoSeeded_RNG rng;


    std::string str= generate_bcrypt(passw,rng,12);

   } 

I compiled it successfully, but when I run it I am getting:

     Starting /home/sh/qt/test-build-desktop/test...

The program has unexpectedly finished.

I have no ideas why I got it(of course, I understand that there is something wrong with stack). But I can't even dare condemn Botan for this. So I expect that I have done somewhere something wrong. Of course, I can leave this library and to try something different. But I have bound myself to this library already(I used decrypt() and ecnrypt()- wealthy), so I don't want to create yet once dependency. I will be really glad and even happy, if somebody gives me tips where my mistake hides.

oops, it's hard to see my screenshots. I reuploaded them:

I can only guess that there is something wrong in Botan.... But it's unbelievable

Answer 1

Well. I wrote a letter to creator of Botan - Jack Lloyd and he answered!!!uraaa. His personal web page is http://www.randombit.net/ .
He suggested that source of error may be usage of headers that are related to different versions of library. i.e. I had a few version of headers, but one library. I mixed them together. Worked code:

#include <botan-1.10/botan/botan.h>
#include <botan-1.10/botan/bcrypt.h>
#include <iostream>
using namespace std;
using namespace Botan;

 int main(int argc, char* argv[])
  {
    LibraryInitializer init;
    AutoSeeded_RNG rng;
    int a=1;
    string strr="4sdfgnglkjnfkdfdfndfglgndlkgdnlkjj";
    cout<<generate_bcrypt(strr, rng,a);
    return 0;
   }

Also I linked explicitly library:
LIBS += -lbotan \
/home/sh/qt/usb_encrypt/libraries/libbotan-1.10.a

Thank you, Jack Lloyd, for such wonderful library.
