Generating hash with Argon2 on Botan results in garbage data and 0xC0000005: Access violation reading location 0x0000000100000000

Question

I'm trying to hash passwords using the C++ cryptography library Botan. I've tried testing out the library using the code below:

#include <iostream>
#include <string>
#include <botan/argon2.h>
#include <botan/system_rng.h>

int main() {
    Botan::System_RNG rng;
    std::string password = "cool_password";

    std::string generated_hash = Botan::argon2_generate_pwhash(password.c_str(), 
    password.length(), rng, 1, 4000, 1); // crash occurs here

    std::cout << generated_hash << "\n";
}

but the code either printed garbage data, or gave me a runtime error: Unhandled exception at 0x00007FFEF11825E0 (ucrtbased.dll) in app.exe: 0xC0000005: Access violation reading location 0x0000000100000000.

What should I do? Using other hashing methods such as Botan::generate_bcrypt() also resulted in the same error.

Answer 1

After 4 hours of painful troubleshooting and rebuilding the library with different compilers over and over, I have found out that Botan does not work properly if "solution configuration" is not set to "Release" rather than "Debug" in Visual Studio.
