Crash on Win 8 64 bit with proxy QNetworkProxyFactory::setUseSystemConfiguration

When trying to use proxy auto configuration, the program crashes on Windows 8 64 bit (32 bit works).

Tried:

QNetworkProxyFactory::setUseSystemConfiguration(true)

also tried:

QNetworkProxyQuery npq(QUrl("http://www.google.com"));
QList<QNetworkProxy> listOfProxies = QNetworkProxyFactory::systemProxyForQuery(npq);
if (listOfProxies.size())
    QNetworkProxy::setApplicationProxy(listOfProxies[0]);

When crash occured i was using mxe for crosscompiling on linux, have no way to try a native 64bit windows build.

Attached is a minimal qtcreator project that fails when compiled with mxe.

Tried current mxe master with gcc 4.9 and qt 5.3.1 and some older 4.8 branch with qt 5.2.1
