Subject: Re: c++/9420: [3.2/3.3/3.4 regression] incomplete type incorrectly reported
X-SW-Source: 2003-01/txt/msg01383.txt.bz2
List-Id: <gcc-prs.sourceware.org>

Old Synopsis: [regression over 2.95] incomplete type incorrectly reported
New Synopsis: [3.2/3.3/3.4 regression] incomplete type incorrectly reported

State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Thu Jan 23 17:13:55 2003
State-Changed-Why:
    True. Very weird problem:
    --------------------------
    enum { E };
    
    template <typename T> struct A {
      static const int a = (E < 0);
    };
    
    template <typename T> class B {
      A<int> b;
    };
    
    struct C {
      C(B<int>);
    };
    
    int operator<(C, C);
    
    A<int> c;
    ----------------------------
    Changing any bit of the code makes the bug go away (e.g.
    changing op< to function foo). Used to work with 2.95, but
    does no longer with 3.2.2 and 3.3 (just accidentially
    ruined my 3.4 installation, but likely to show same problem).
    
    W.
