[Bug lto/42653] New: ICE with -g and -flto (requires both flags to crash)

["baldrick at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

$ g++ -c -flto -g fltog.ii
fltog.ii: In member function ?MCIListener?:
fltog.ii:25:3: internal compiler error: tree check: expected class ?type?, have
?declaration? (function_decl) in gen_type_die_with_usage, at dwarf2out.c:18747

Occurs with top-of-tree g++-4.5.

Testcase fltog.ii:

namespace llvm
{
  class Function;
  class MachineCodeInfo;
  class ExecutionEngine
  {
  };
  class JIT:public ExecutionEngine
  {
    void runJITOnFunction (Function * F, MachineCodeInfo * MCI = 0);
  };
  class JITEventListener
  {
  public:JITEventListener ()
    {
    } virtual ~JITEventListener ();
  };
}

using namespace llvm;
void
JIT::runJITOnFunction (Function * F, MachineCodeInfo * MCI)
{
  class MCIListener:public JITEventListener
  {
    MachineCodeInfo *const MCI;
  public:  MCIListener (MachineCodeInfo * mci):MCI (mci)
    {
  }};
}
