$ 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)
    {
  }};
}

Yep - -g and -flto are very experimental.

Compiling the GCC testsuite with -flto and -g, it turns out that
g++.dg/debug/dwarf2/pr41063.C already shows this problem.

Yes, there are a bunch of known ICEs with running the C++ testsuite with
-g -flto.
