>Description:
The following buggy code crashes the compiler with an internal
compiler error. 


>How-To-Repeat:
Source file te.C:x
class A : public E     
{
public:
    A(D *d=0);
    void g(); 
private:
    B *b;            
};


A::A(D *d) : E()
{
  b = new B;  
  z(h(const B &));
} 

void A::g()
{
}

Compiling the program:
g++ -c te.C -save-temps
te.C:2: parse error before '{' token
te.C:6: parse error before 'CPP_NAME' token
te.C:11: `D' was not declared in this scope
te.C:11: `d' was not declared in this scope
te.C:11: structure `A' not yet defined
te.C:11: invalid declarator
te.C:11: syntax error before ':' token
te.C:14: parse error before '&' token
te.C:14: ISO C++ forbids declaration of `z' with no type
te.C: In function `int z(...)':
te.C:18: invalid use of undefined type `class A'
te.C:1: forward declaration of `class A'
te.C: In member function `void A::g()':
te.C:19: Internal error #123.
te.C:19: Internal compiler error in pop_binding_level, at cp/decl.c:609
confused by earlier errors, bailing out
