>Description:
Error in dump class hiearchy file generated for template class's
virutal destructor.  This only occurs for template classes.

Options given when GCC was configured/built:
Configured with: /build/gcc/gcc-3.2/configure -prefix=/.../torolab.ibm.com/fs/pr
oj/p0/vabld/run/gcc/linux_ppc/3.2.0 -enable-threads=posix -enable-languages=c,c+
+ -disable-shared
Thread model: posix

Sourc code for a.cpp:
------------------------------------------------
template <class T> struct A {
  virtual ~A () {}
};

A<int> a;
------------------------------------------------

Actual class hierarchy file (a.cpp.class):
------------------------------------------------
Vtable for A<int>
A<int>::_ZTV1AIiE: 4 entries
0     0
4     &_ZTI1AIiE
8     A<T>::A() [with T = int]
12    A<T>::A() [with T = int]

Class A<int>
   size=4 align=4
A<int> (0x40092600) 0 nearly-empty
    vptr=((&A<int>::_ZTV1AIiE) + 8)
------------------------------------------------

Expected Behaviour:
- expected the "Vtable for A<int>" entries contains class A's destructor,
  not constructor

a.ii generated with -save-temps option
------------------------------------------------
# 1 "a.cpp"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "a.cpp"
template <class T> struct A {
  virtual ~A () {}
};

A<int> a;
------------------------------------------------
>How-To-Repeat:
1. g++ -fdump-class-hierarchy -c a.cpp
2. cat a.cpp.class
