   2 // This test is from Nigel Perry, Bugzilla #77060
   3 //
   4 // The issue here was that in the past we used to emit the
   5 // Scope initialization on first use, which is wrong as illustrated
   6 // in this test (the shared scope is not initialized for differnt
   7 // code paths).
   8 //
   9 // This test is a running test, ensuring that it runs
