// Test that the destructor for a temporary passed by value isn't run // until end of full-expression, as per [class.copy]: // Whenever a temporary class object is copied using a copy constructor, // and this object and the copy have the same cv-unqualified type, an // implementation is permitted to treat the original and the copy as two // different ways of referring to the same object and not perform a copy // at all, even if the class copy constructor or destructor have side // effects.... In these cases, the // object is destroyed at the later of times when the original and the // copy would have been destroyed without the optimization. // Here, the temporary would be destroyed later than the parm, so either we // must suppress the optimization in this case or destroy value parms in the // caller. // Split into pieces for binary compatibility testing October 2002 extern void elide1_x (void); int main () { elide1_x (); }
