--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
class Module : public SyntaxElement {
public:
        Module() = default;
        bool hasCalleesFor(IntrusiveRefCntPtr<Function> func) const
        { return true; }
};


void Context::setAvailableCallees() {
        if(!M->hasCalleesFor(F)) return;
}

This creates an IntrusiveRefCntPtr<Function> which owns F, and so at the end of
the statement the smart pointer deletes F.

Any later use of that pointer (via this->F or the global func) is undefined.
