Segmentation fault for malformed svg (loop)

This piece of code gives Segmentation Fault for a particular ill-formed svg: 

#include <QSize>
#include <QImage>
#include <QString>
int main(int argc, char *argv[])
{
 QImage* image = new QImage(QString::fromUtf8("malformed.svg"));
}

 The svg is as simple as it gets (with a loop in it):

<svg>
 <g id="0"><use xlink:href="#0" /></g>
</svg>

Works fine in Qt 5.4 & Qt5.8.0. Fails for  5.5.1, 5.6.2 & 5.6.3

Seems pretty similar to: https://bugreports.qt.io/browse/QTBUG-35387
