           Summary: [llvmg++] Cannot use pointer to member to initialize
                    global
           Product: tools
           Version: 1.0
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: llvm-g++
        AssignedTo: sabre at nondot.org
        ReportedBy: sabre at nondot.org


This testcase:

struct Gfx {
  void opMoveSetShowText();
};

struct Operator {
  void (Gfx::*func)();
};

Operator opTab[] = {
  {&Gfx::opMoveSetShowText},
};


Inspires this lovely evocation from llvmg++:
