>Description:
If a template contains a static array, and the dimension
of the array is defined by a const static member with initializer,
and the dimension is used in the definition of the static array,
g++ gives an error "conflicting types"; which probably means
that the value of the dimension is lost.
>How-To-Repeat:
template <class T>
class X
{
static const int a = 5;
static T b[a];
};
template <class T> T X<T>::b[X::a];
>Fix:
The dimension can be left out in the definition of the static member.
