            Bug ID: 37362
           Summary: -Wglobal-constructors false positive
           Product: clang
           Version: trunk
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: dave at znu.io
                CC: dgregor at apple.com, llvm-bugs at lists.llvm.org

John McCall asked me to file the following code reduction. Top-of-tree
generates a -Wglobal-constructors warning with the following code, but no
actual constructor is emitted.

struct Once {
  unsigned value;
  constexpr Once() : value(0) {}
};

template<typename T>
class Lazy {
  T t;
  Once once;
public:
  constexpr Lazy() = default;
};

Lazy<unsigned> lazy;
