// g++ 1.37.1 bug 900520_06
// When an object of a class type is passed into a formal parameter of the
// same class type (in a function call) the language definition calls for
// this action to be treated like any other form of an initialization of
// an object of the given class type.
// g++ fails however to invoke the (compiler-supplied) copy constructor for
// the class type when a parameter of the class type is passed as an
// actual parameter.
// This causes the following program to exit with a non-zero exit status.
// cfront 2.0 passes this test.
