// { dg-do run  }
// This tests two things:
// 1. there is an annoying warning.
// singleton.C:26: warning: `class singleton' only defines private constructors and has no friends
// egcs fails to see that there is a public static accessor function.
// 2. the program crashes, because apparently the static variable s in
// singleton::instance() is considered constructed although the ctor
// exited via an exception. (crash changed to nonzero return here)
