// { 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)
