Gtk::Action subclass with Visual C

[Yann LEYDIER <yann leydier info>]

Hi,

I created two Action subclasses (one for ScaleButton and another for 
ColorButton). It works fine on linux (Ubuntu 10.04 and Debian Sid). 
However it crashes with Visual C++ 2008.

My project uses stlport (to avoid DLL restrictions on the standard 
library) so I compiled libsigc++, glibmm, cairomm, pangomm, atkmm and 
gtkmm (2.22.0) with Stlport 5.2.1.

I isolated the problem (or at least, one problem) in a small code sample 
pasted at the end of the message. The program crashes (access violation) 
at exit in Gtk::Action::~Action(), which is an empty method !

Moreover, Visual C++'s debugger prints a wrong address for "this" 
whereas a "cout << this" in my destructor prints the good address.

Running the program with valgrind on linux displays no error.

Does anyone know what can cause such a crash ? It is hard to find 
documentation or examples on how to create custom actions, so I don't 
know if I did something wrong.

Many thanks,
Yann
