 Hi,
 
 the parser chokes on the following illegal code snippet (X is
 undefined):
 
 ---------------------------snip here---------------------------
 struct foo
 {
     X x;
 
     foo(X)              {}
     foo(X y, int) : x() {}
 };
 ---------------------------snip here---------------------------
 
 The error messages with gcc 3.1 are:
 
 bug.cc:3: 'X' is used as a type, but is not defined as a type.
 bug.cc:5: parse error before `)' token
 bug.cc:5: missing ';' before right brace
 bug.cc:6: `X' was not declared in this scope
 bug.cc:6: parse error before `,' token
 bug.cc:6: ISO C++ forbids defining types within return type
 bug.cc:6: semicolon missing after declaration of `struct foo'
 bug.cc: In function `int foo(...)':
 bug.cc:6: only constructors take base initializers
 bug.cc:6: confused by earlier errors, bailing out
 
 Gcc 2.95.x and 3.0.x handle the situation gracefully. Gcc 3.1 and 3.2
 produce "confused by earlier errors, bailing out" and the main trunk
 ICEs (checked on i686-pc-linux-gnu and mips-sgi-irix6.5).
