 Hi,
 
 the offending code can be reduced to
 
 template<unsigned>   struct A {};
 template<typename T> struct B { A<sizeof(+int())> a; };
 
 These two lines will crash gcc 3.0.x and gcc 3.1 20011210
 on i686-pc-linux-gnu and mips-sgi-irix6.5.
 Just compile with "g++ -c".
 
 Greetings,
 Volker Reichelt
