State-Changed-Why:
    The bug is only in SuSE's version of gcc 3.2, not in the FSF version.
    Therefore, I close the PR.
    
    Some details:
    After applying the patches from the SuSE-distribution to the FSF 3.2 version
    and bootstrapping the compiler for i486-pc-linux-gnu I can reproduce the bug.
    (In fact the first 42 ;-) patches are sufficient to trigger the bug, probably
    much less, but I didn't investigate further.) Bootstrapping for
    i686-pc-linux-gnu does *not* trigger the bug.
    
    A shorter testcase that causes the ICE in SuSE's compiler is the following:
    
    ---------------------------snip here--------------------------
    template <class T> void bar(T&, T, int, int, int) {}
    
    template <class T> struct A
    {
      void foo() const{ T t; bar(t, t, 0, 0, 0); }
    };
    
    class B
    {
      double d;
      char   c;
    };
    
    template struct A<B>;
    ---------------------------snip here--------------------------
    
    BTW, a similar bug is 8240.
