Synopsis: ICE in tree check: expected var_decl, have error_mark in tsubst_decl, at cp/pt.c:5987

State-Changed-From-To: open->analyzed
State-Changed-By: cae
State-Changed-When: Sun May 18 17:28:32 2003
State-Changed-Why:
    Redux:
    
    template <bool Cond>
            struct A { };
    template <typename p>
            struct B { typedef int car; };
    template <typename Top>
            struct C {
                    template <int pos>
                    typename B<typename A<INVALID>::result>::car f ();
            };
    C<int> x;
    
    I get a different message with 3.3-release due to a missing
    --enable-checking. This redux also ICEs 3.4 but at a different
    line number.
    
    Output of 3.3 WITHOUT treecheck output:
    10716.cc: In instantiation of `C<int>':
    10716.cc:10:   instantiated from here
    10716.cc:8: error: `INVALID' was not declared in this scope
    10716.cc:8: confused by earlier errors, bailing out
    
    Output of somewhat dated 3.4 WITH tree checking:
    10716.cc:8: error: `INVALID' has not been declared
    10716.cc:8: error: template argument 1 is invalid
    10716.cc:8: internal compiler error: tree check: expected class 't', have 'x' (
       error_mark) in make_typename_type, at cp/decl.c:5498
