In attempting to get IV-3.0 running on a SONY news using Gcc-2.0 I
encountered a bug in the compiler. This bug is prompted by the following
simplified example of code. I cannot fathom what I need to
change to get the compiler to accept this code or if it is valid code.

The compiler fails with an abort inside an assertation in cp-cvt.c at
line 1188.

--------------------- Code follows ---------------------------------------
class ivResource   {
public:
    virtual ~ivResource  ();
};
class StateVar {
public:
    virtual ~StateVar();
};
class SharedName : public StateVar, virtual public ivResource   {
};
class MemberSharedName : public SharedName {
};
class ButtonSharedName : public SharedName {
};
class UControl : virtual public ivResource   {
};
class IBEditor  {
public:
    virtual ~IBEditor();
private:
    UControl* _tab;
};
IBEditor::~IBEditor () {
    delete _tab;
}
