// { dg-do run  }

// 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.
