>Description:

>How-To-Repeat:
Put following into foo.cc
include <list>

class   Foo
{
public:
    int             x;
    std::list<Foo>  children;
};

then

g++ -c foo.cc

(note: Works fine on Linux x86)
>Fix:
Change std::list<Foo> children to std::list<Foo> *children
and fix code that references it. ugh
