      SSL Connection crashes all the time in Android 6 (tested only with one device so far)

      test.cpp
      QSslSocket::supportsSsl() // true
QSslSocket::sslLibraryVersionString(); // "BoringSSL"
QSslSocket::sslLibraryBuildVersionString(); // "OpenSSL 1.0.1j 15 Oct 2014"

QSslSocket sslSocket;
sslSocket.setProtocol(QSsl::SecureProtocols);
QSslCertificate cert = QSslCertificate(ourcacert);
QList<QSslCertificate> certs;
certs.append(cert);
sslSocket.setCaCertificates(certs);
sslSocket.connectToHostEncrypted("xyz.com", 443);

bool res = sslSocket.waitForConnected(); // place where it crashes
...

      Error happens even if I do non blocking connection, dumps are same, only difference in non blocking it comes from EventLoop, in blocking it crashes immediately

      ....

      this logic worked fine until Android 6.
