I built Qt 5.10.1 myself, linked against OpenSSL 1.1.0h. This was needed due to improved multithreading capabilities in OSSL 1.1.0.
This is the fragment of code I use:
manager = new QNetworkAccessManager(this);
std::string Loader::getContent(std::string inURL)\{
std::string result = "";
url = QUrl(inURL.c_str());
while(true)\{
QNetworkRequest request = QNetworkRequest(url);
QEventLoop loop;
connect(manager, SIGNAL(finished(QNetworkReply*)),&loop, SLOT(quit()));
QNetworkReply *netReply = manager->get(request);
loop.exec();
if(netReply->error() == QNetworkReply::NoError)\{
result = QByteArray(netReply->readAll()).constData();
netReply->deleteLater();
break;
}
else\{
DebugMsg << "Error loading: " << inURL << ". Retrying";
netReply->deleteLater();
}
}
return result;
}
Your help is kindly requested.I built Qt 5.10.1 myself, linked against OpenSSL 1.1.0h. This was needed due to improved multithreading capabilities in OSSL 1.1.0.

Description
I am using QNAM to crawl sites, which are SSL encrypted.
For example: https://sofifa.com
Now I see a memory leak in valgrind, coming from QSslCertificate:
==5614== 26 bytes in 2 blocks are definitely lost in loss record 233 of 1,060
==5614== at 0x4C2DB8F: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
