If it was only my application, but wxLua seems to have the same problem 
here.
Crash in same stack, with class name wxLuaDebugServer.
Same wxLuaedit, but there it is wxLuaShell.

This is using the VCproject files like in CVS.

In wxArt2D i use Cmake generated project files,  so this  is no the  
problem ( linking order etc. ).

Oke i see, was wondering already why ;-) I just a copy paster here, 
since i do not understand how everything works together. Once i can 
actually run something, i think things will become more clear to me.
Still i very much hope you will find some time to make a state ot the 
art sample, to demo how it is done.
Not that i what to be pushing ;-)

Oke, i understand now. Although i don't get that reference counting 
mechanism. ( like brush and pens in wxWidgets right?)
Is it possible that one wants to derive from wxLuaState? I wonder if  
plain smart pointers would have bin easier/better or not? Not that i 
know, but in wxArt2D i had problems deriving from wxBrush because of this.
In any case, i hope my problems or not due to this.

It is! But constantly some othere classname, depending upon the first on 
added in some app.

I think too, and it is related to wxLuaState here :-(

How to do that?

I will now try to test wxLua on Vc.Net, see if the problem is the same 
there.

How is it possible i have this problem and you don't?

The only warning i do get is the next, but this doe not harm i think.
Linking...
LINK : warning LNK4098: defaultlib "MSVCRT" conflicts with use of other 
libs; use /NODEFAULTLIB:library

wxluaedit.exe - 0 error(s), 1 warning(s)
