Synopsis: gcc hangs when static declared twice in templated class

State-Changed-From-To: open->analyzed
State-Changed-By: cae
State-Changed-When: Mon Feb 10 21:57:45 2003
State-Changed-Why:
    Confrimed. All supported versions fail to compile this, 3.2.2 gives
    an endless loop, 3.3 and 3.4 give an ICE at the same place. Here's 
    a minimal legal example, it is possible to remove the out of class
    definition of the static member without the ICE going away.
    ---------------- cut -----------------
    template <class R>
    struct A {
    	static int _test;
    	static int _test;
    };
    template <class R> int A<R>::_test = 0;
    struct B : public A <int> { };
    ---------------- cut -----------------
    9649.cc: In instantiation of `A<int>':
    9649.cc:7:   instantiated from here
    9649.cc:4: internal compiler error: in finish_member_declaration, at 
       cp/semantics.c:1868

>Description:
If you declare a static data member twice, gcc will hang while compiling.  Looks like stuck in a loop to me - top shows gcc sucking 99.9% of cpu.

aaa.h
----------
template <class R, class I> class Aaa
{
public: // methods
    Aaa() {}
    virtual ~Aaa() {}
    static int _test;
    static int _test;
};                               
template < class R, class I > int Aaa<R,I>::_test;

-----------
aab.h
-----------
#include "aaa.h"
class Aab : public Aaa< int, float >
{
public: // methods
    Aab();
    virtual ~Aab();
};

------------
aab.cpp
------------
#include "aab.h"
Aab::Aab(){} 
Aab::~Aab(){}
>How-To-Repeat:
Compile the code included in the description:

gcc aab.cpp
