Boost Test and QtTest memory access violation with Botan

Question

I've been struggling with this and so far couldn't make it work. A simple main using botan works fine, but when i put the same code in a unittest it fails.

// keygeneration_test.cpp

#define BOOST_TEST_DYN_LINK 
#include <boost/test/unit_test.hpp> // shuold use this one if using dynamic linking
#include <botan\botan.h>
#include <botan\rsa.h>

BOOST_AUTO_TEST_SUITE(keygeneration_suite)

BOOST_AUTO_TEST_CASE(rsa_key_generation)
{
    BOOST_TEST_MESSAGE("generating key");
    try
    {
        Botan::LibraryInitializer init;

        Botan::AutoSeeded_RNG rng;
        rng.reseed(10096);
        Botan::RSA_PrivateKey rsaPrivate(rng, 1024);
    }
    catch (std::exception& e)
    {
        BOOST_TEST_MESSAGE(e.what());
    }
}

BOOST_AUTO_TEST_SUITE_END()

--

// main.cpp

#define BOOST_TEST_DYN_LINK
#define BOOST_TEST_MODULE cryptography test //module define should be only here, it takes care of creating entry point

#include <boost/test/unit_test.hpp> // should use this one if using dynamic linking

I then tried putting the init in the main entry point like this:

//main.cpp

#define BOOST_TEST_DYN_LINK // Make the exe link dynamically
#define BOOST_TEST_NO_MAIN

#include <boost/test/unit_test.hpp> // should use this one if using dynamic linking

#include <botan\botan.h>

bool init_function()
{
    return true;
}

int main(int argc, char* argv[])
{
    Botan::LibraryInitializer init;
    return boost::unit_test::unit_test_main(&init_function, argc, argv);
}

They both show the same error:

Running 1 test case... unknown location(0): fatal error in "rsa_key_generation": memory access violation occurred at address 0x00141000, while attempting to read inaccessible data

*** 1 failure detected in test suite "cryptography test" Detected memory leaks! Dumping objects -> {670} normal block at 0x0000000000221380, 16 bytes long. Data: 78 EA 13 00 00 00 00 00 00 00 00 00 00 00 00 00 Object dump complete.

Just for the record, a simple test for compression that i tried or whatever i did works fine, but when i try to create a test with botan initialization it fails no matter what i try.

Edit: I've tried with Qt Test and the same happens. Its is really weird. Has anyone experienced something like this? Could anyone reproduce this?

Found the annoying problem. Code Generation was set to Multi-threaded DEBUG DLL. For some reason changing to Multi-threaded DLL makes it work. I guess maybe because botan was compiled for release. (it would be nice to have a hint or suggestion from the compiler...)
