Does your stdafx.h have all of the includes it has per default? It
doesn't seem so to me. Visual Studio needs some strange headers to be
able to compile. Add a new project and copy those includes from there to

Hello,
I think I need help with a program I wrote. It uses gtkmm and it
sometimes crashes without a reason when I start it (segmentation fault).
I tried to let it crash when started with debugging and it stopped in

Okay it seems that this problem is fixed. I checked if a Glib::RefPtr
equaled NULL in the constructor, before it got an initial value. :D
I think that thing was static before so it could have made sense sometime.
Anyway, thanks Yann :)

You're problem is that your myLabel class isn't a label but a window.
You're deriving it from Gtk::Window.
Normally, you wouldn't derive your own label, I wonder what you wanted

There's a simple fix for that: Don't use -Weffc++. The C++ standard

without, or with only a few warnings when having that flag enabled. For
example, it warns you about class members that are not explicitly

What you want is resize():
