   1 // This tests a crash which occured under very specific circumstances. The
   2 // interesting aspects of this test are:
   3 // - we print a global variable from one compile unit
   4 // - we are stopped in a member function of a class in a namespace
   5 // - that namespace is also present in a third file, which also has a global
   6 //   variable
