Segmentation fault while using QCA

I’ve been getting the following segmentation fault when compiling: “The inferior stopped because it received a signal from the Operating System. Signal name : SIGSEGV Signal meaning : Segmentation fault” Stacktrace: 0 lockInline qmutex.h 187 0×7ffff7b3f33b 1 QMutexLocker qmutex.h 109 0×7ffff7b3f33b 2 QCA::init qca_core.cpp 185 0×7ffff7b3f33b 3 RegistrationDialog::verifyKey registrationdialog.cpp 60 0×4b15e8 following is the function: bool RegistrationDialog::verifyKey(QString Registeredkey) {     QString generated_key;     QString mac_address = getMacAddress();       // the Initializer object sets things up, and     // also does cleanup when it goes out of scope     QCA::Initializer init = QCA::Initializer();       QString PassKey = "iXBv9TobQ545Fc4AB";     QCA::SymmetricKey key(16);     QCA::InitializationVector iv(PassKey.toLatin1());     QCA::Cipher cipher(QString( "des" ), QCA::Cipher::CBC, QCA::Cipher::PKCS7, QCA::Encode, key, iv);         // we use the first argument if provided, or     // use "hello" if no arguments //    QCA::SecureArray arg = (argc >= 2) ? argv[1] : "hello";     QCA::SecureArray arg = mac_address.toUtf8();       // DES testing     if(!QCA::isSupported("des-cbc-pkcs7"))         printf("DES-CBC not supported!\n");     else {           QCA::SecureArray u = cipher.update(arg);           // We need to check if that update() call worked.         if (!cipher.ok()) {             qDebug()<<"Update failed";         }           QCA::SecureArray f = cipher.final();           // Check if the final() call worked         if (!cipher.ok()) {             qDebug()<<"Final failed";         }           generated_key = qPrintable(QCA::arrayToHex(f.toByteArray()));           if ( Registeredkey == generated_key ) {             return true;         } else {             qDebug()<<"not true!";             return false;         }     }       return false; }
