class foo { int a; };
class foob : public foo { int b; };
foo afoo;
foo* afooPtr = &afoo;
foob* afoobPtr = (foob*) afooPtr;
foo& afooRef = afoo;
foob& afoobRef = (foob&) afooRef;  // Ok with g++1.37.0, rejected by g++1.37.2-
main(){}

This code compiles well with CC 2.0 on a Sun and with Zortech 2.1, but fails
with g++1.37.2-. Is it legal ?
