Hi,

The program below was reduced from our latest implementation of
numeric_limits. aCC 3 (but not 6) chokes on it for some strange
reason. I can't think of a workaround -- do you have any ideas?

Martin

$ cat t.cpp && aCC -AA -V -c t.cpp
/*   1 */ template <class T> struct S { static const int i = 0; };
/*   2 */ template <class T> struct S<const T>: S<T> { };
/*   3 */ template <class T> const int S<T>::i;
/*   4 */ template <> struct S<int> { static const int i = 1; };
/*   5 */ const int S<int>::i;
aCC: HP ANSI C++ B3910B A.03.63
Error 643: "t.cpp", line 3 # Template type parameter 'i' may not be 
redeclared within the scope of the template.
    template <class T> const int S<T>::i;
                       ^^^^^^^^^^^^^^^^^^
Error 309: "t.cpp", line 3 # Only classes, functions, and static data 
members may be used as templates.
    template <class T> const int S<T>::i;
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Error 445: "t.cpp", line 3 # Cannot recover from earlier errors.
    template <class T> const int S<T>::i;
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
