             Bug #: 50973
           Summary: [C++11] internal compiler error defaulted destructor
                    virtual inheritance
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jarrydb@cse.unsw.edu.au


The following code causes an internal compiler error:


class HD
{
  public:
  virtual ~HD() {};
};
class InputHD : public virtual HD
{
};
class OutputHD : public virtual HD
{
};
class IOHD : public InputHD, public OutputHD
{
};
template <typename T, unsigned int N>
class ArrayNHD : public IOHD
{
  public:
  ~ArrayNHD() = default;
};
class TLText
{
  ~TLText();
  ArrayNHD<int, 1>* m_argsHD;
};
TLText::~TLText()
{
  delete m_argsHD;
}
