// { dg-do assemble }
// g++ 1.36.1 bug 900121_02
// Assignment of structs is defined as memberwise assignment,
// however g++ (1.36.2) and Cfront 2.0 differ on the definition
// of assignment for unions.
// (NOTE: Stroustrup now says that assignment of unions which contain either
// members or sub-members (base classes are not allowed for unions) which
// have non-default assignment operators defined for them will be illegal
// in future.)
// g++ (1.36.2) on the other hand, accepts this program without errors.
// keywords: unions, operator=, inheritance, members
