All works well unless you start using dynamic_cast within a ctor of a 
derived class

e.g.

struct A
{  A() { this->a_method_which_uses_dynamic_cast(); }
};

struct B
{  int x;
    B() : A(), x(1) {}
}

this will crash. It will not crash if you remove the x (the compile 
optimizes B away) or if you call a_method_which_uses_dynamic_cast 
after A() has ended (e.g. in a member or inside B()).

Since this is clearly a compiler bug and any workarounds are quite ugly 
and most up to date distributions ship with g++-3.2 I'd recommend to 
upgrade the compiler. You really get a better environment, 2.95 is 
broken in many ways (e.g. standard conformance), produces larger code 
and will die soon (hopefully).

I would accept a patch which moves the widget creation and customization 
into an init function (actually add() uses dynamic_cast()), but I bet 
the effort is better put into upgrading your compiler. Of course you can 
replace the ctor of foo_glade by init and call that function from your 
foo ctor but this means patching the generated file by hand (or patch).
