Responsible-Changed-By: bangerth
Responsible-Changed-When: Tue Apr 29 19:55:14 2003
Responsible-Changed-Why:
    Might be due to a patch of yours
State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Tue Apr 29 19:55:14 2003
State-Changed-Why:
    Confirmed. A regression in 3.3 and 3.4 w.r.t 3.2. Reduced
    code is this:
    ---------------------------
    template <class T> struct C {
      ~C();
    };
    template <class T> C<T>::~C() {}
    
    struct X {
        C<X> *p;
        ~X() { delete p; }
    };
    
    template class C<X>;
    C<X> x;
    
    int main () {}
    --------------------------------
    g/x> /home/bangerth/bin/gcc-3.3-pre/bin/c++ x.cc --no-implicit-templates
    /tmp/cckNVmwH.o: In function `__static_initialization_and_destruction_0(int, int)':
    /tmp/cckNVmwH.o(.text+0x3e): undefined reference to `C<X>::~C [in-charge]()'
    
    (and same with 3.4).
