 Hi,
 
 the problem can be reduced to the following code snippet:
 
 -------------------------snip here---------------------
 template <typename T> struct A
 {
     void foo () const {}
     char A;
 };
 
 void bar() { A<void>().foo(); }
 -------------------------snip here---------------------
 
 The code crashes with gcc 3.0.x, 3.1, 3.2, and the main trunk (as of
 20020923). Checked on mips-sgi-irix6.5 and i686-pc-linux-gnu.
 
 The error is:
 
 PR7647.cc: In instantiation of `void A<T>::foo() const [with T = void]':
 PR7647.cc:7:   instantiated from here
 PR7647.cc:3: internal compiler error: Segmentation fault
 Please submit a full bug report, [etc.]
 
 With gcc 2.95.3 I get:
 
 PR7647.cc:4: ANSI C++ forbids data member `A' with same name as enclosing class
 PR7647.cc: In instantiation of `A<void>::foo() const':
 PR7647.cc:7:   instantiated from here
 PR7647.cc:3: confused by earlier errors, bailing out
 
 Greetings,
