Iirc I copied from OSGGeometry. I felt it might be wise to copy from a class
that is also derived from NodeCore :-)

That is correct, however I am using Visual Studio 2008 and I think you can't
do much wrong anymore here as Single-Threaded libraries are long gone. I am
building Multithreaded DLL Debug and the compile time parameters are:
/Od /I <stripped a lot of include paths here> /D "WIN32" /D "_WINDOWS" /D
"_DEBUG" /D "_OSG_HAVE_CONFIGURED_H_" /D "OSG_BUILD_DLL" /D "OSG_DEBUG" /D
"OSG_WITH_GLUT" /D "OSG_WITH_GIF" /D "OSG_WITH_TIF" /D "OSG_WITH_JPG" /D
"GLEW_STATIC" /D "GALE_NO_AUTO_LINK" /D "_EMBEDDED_MANIFEST" /D
"_CRT_SECURE_NO_WARNINGS" /D "_AFXDLL" /D "_MBCS" /Gm /EHsc /RTC1 /MDd
/Yu"stdafx.h" /Fp"../../intermediate\RibbonGUI/Debug.pch"
/Fo"../../intermediate\RibbonGUI/Debug/"
/Fd"../../intermediate\RibbonGUI/Debug/" /W3 /nologo /c /ZI /TP
/errorReport:prompt
Now as I look at it, I see that all the defines are from the 1.8 build, but
I have no idea what needs to be defined there.

I don't see how that would help in my case, as I am building an application
(well actually two applications with different GUIs) using OpenSG. But I
will have a look at it.

I too guessed that it might be the first and walked through the code using
the debugger. It is indeed the first of my nodes, but it is not the first
assignment to a string.

Is the content of _fcdXML (in FieldContainerType) crucial?
For the record, this is what my definition looks like:
FieldContainerType SecstrucNodeCore::_type(
"SecstrucRenderNode", "NodeCore", NULL, 0,
reinterpret_cast<PrototypeCreateF>(&SecstrucNodeCore::createEmpty),
SecstrucNodeCore::initMethod);
It can't have anything to do with the implementation of createEmpty as far
as I can see. It crashes in the initialize list of FieldContainerType,
before the actual constructor.

I guessed as much, but all the attributes in the xml files are undocumented

No problems here yet, I was just guessing. I need the app to NOT crash
before I can start synchronizing :-)
