             Bug #: 51620
           Summary: [c++0x] [4.6/4.7 Regression] ICE with private
                    destructor
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: reichelt@gcc.gnu.org


The following invalid code snippet triggers an ICE since GCC 4.6.0 when
compiled with "-std=c++0x":

===========================
template<int> class A
{
  virtual ~A();
};

struct B : A<0>, A<1>
{
  B() {}
};
===========================

bug.cc:6:8: error: deleted function 'virtual B::~B()'
bug.cc:3:11: error: overriding non-deleted function 'A<<anonymous> >::~A()
[with int <anonymous> = 0]'
bug.cc:6:8: note: 'virtual B::~B()' is implicitly deleted because the default
definition would be ill-formed:
bug.cc:3:11: error: 'A<<anonymous> >::~A() [with int <anonymous> = 0]' is
private
bug.cc:6:8: error: within this context
bug.cc:3:11: error: 'A<<anonymous> >::~A() [with int <anonymous> = 1]' is
private
bug.cc:6:8: error: within this context
bug.cc:6:8: error: deleted function 'virtual B::~B()'
bug.cc:3:11: error: overriding non-deleted function 'A<<anonymous> >::~A()
[with int <anonymous> = 1]'
bug.cc: In constructor 'B::B()':
bug.cc:3:11: error: 'A<<anonymous> >::~A() [with int <anonymous> = 0]' is
private
bug.cc:8:7: error: within this context
bug.cc:3:11: error: 'A<<anonymous> >::~A() [with int <anonymous> = 1]' is
private
bug.cc:8:7: error: within this context
bug.cc: At global scope:
bug.cc:9:2: error: use of deleted function 'virtual B::~B()'
bug.cc:9:2: error: use of deleted function 'virtual B::~B()'
bug.cc:9:2: error: use of deleted function 'virtual B::~B()'
bug.cc:9:2: error: use of deleted function 'void B::_ZThn4_N1BD1Ev()'
bug.cc:6:8: note: 'void B::_ZThn4_N1BD1Ev()' is implicitly deleted because the
default definition would be ill-formed:
bug.cc:6:8: internal compiler error: in synthesized_method_walk, at
cp/method.c:1168
Please submit a full bug report, [etc.]

In addition, the first part of the message is duplicated, "use of deleted
function 'virtual B::~B()'" appears 3 times, and "B::_ZThn4_N1BD1Ev()" is not
very meaningful to the user.
