Crash in VS 2017 when loading SVG

[JFreyberger]

Hi,

I just created a minimal project in VS2017, added libsvgren via NuGet and tested your minimal example. Whenever I try to load any svg (tried various also from your examples) it crashes with access violation ("_Parent_proxy" was "0xCCCCCCCC". ) in xutility line 164:

if _ITERATOR_DEBUG_LEVEL == 2

        if (_Myproxy != _Parent_proxy)
            {   // change parentage
            _Lockit _Lock(_LOCK_DEBUG);
            _Orphan_me();

=> _Mynextiter = _Parent_proxy->_Myfirstiter; _Parent_proxy->_Myfirstiter = this; _Myproxy = _Parent_proxy; }

The call stack looks like this:

here's my packages.config:

<?xml version="1.0" encoding="utf-8"?>

Probably I'm just missing some compiler option etc. but I don't know which. Do you have any ideas?

Thanks and best regards, Johannes

... sorry. I didn't update to the latest libraries. Now there's no crash anymore :-)

Great!
