Given this code:
template<typename T, T N> struct int_ {
static const T value = N;
typedef int_< T, static_cast<T>(value+1) > next;
};
GCC says:
intconst2.cc:3: error: template argument 2 is invalid
It works if you replace "value" with "N".
Possibly related to recent changes to C++ parser disallow floating-point
literals in integral-constant expressions? Appeared around the same time.
This causes compilation failures in Boost.MPL
