State-Changed-When: Thu May 16 07:01:28 2002
State-Changed-Why:
    Fixed in the main trunk.  It won't be fixed in 3.1 branch 
    as stability is the main focus there.

 Hi,
 
 on can reduce the testcase a little more:
 
 --------------------------snip here-------------------------------
 template <int N> struct HoldInt {};
 
 template <class A, class B> struct Add;
 
 template <int N, int M> struct Add< HoldInt<N>, HoldInt<M> > {};
 
 template <int N>        struct Add< HoldInt<N>, HoldInt<-N> > {};
 
 Add< HoldInt<1>, HoldInt<-1> > a;
 --------------------------snip here-------------------------------
 
 By the way, both testcases not only crash gcc but even SGI's native
 compiler, so they seem to be a real compiler-killers ;-)
 
 Greetings,
 Volker Reichelt
