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

// UNSUPPORTED: system-darwin, system-windows
