Just wondering, which GUI framework are you referring to?

wxWidgets for Windows. It's not a problem with "normal" use but I tried to use
it as underlying implementation of some more general functionality. The code is
peppered with macros that generate rather unsafe static initializations (it blew
up for my use, I started fixing things, but finally gave up, it was too much).

Hm, interesting. I wasn't sure about which GUI library so I had to search among
old projects. And when I finally found that one it had another interesting file:

<code>
struct Foo {};
struct Naughty {};

struct X: Naughty, Foo
{
#ifdef CX
     X(): Naughty(), Foo() {}
#else
     X() {}
#endif
};

int main()
{
     X* p = new X;
     delete p; // !!! defined(CX) blows up with MSVC 7.1 debug build.
}
</code>
