+// 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 nonzero exit status.
+
+// cfront 2.0 passes this test.
