the following programm
-----------------------------------------------
#include <iostream>
struct A
{
A() : value(0) {}
int value;
};
template<class T>
struct B
{
static A a;
};
template<class T> A B<T>::a;
//template<> A B<int>::a;
template<class T>
struct C
{
C() { B<int>::a.value = 1; }
};
C<float> c;
main()
{
std::cout << B<int>::a.value << std::endl;
}
-------------------------------------------------
prints 0 instead of expected 1.
It is important that C is template. Otherwise (if C is ordinary class) the
output is 1.
If I use "template<> A B<int>::a;" instead of "template<class T> A B<T>::a;" I
got linker error: undefined reference to 'B<int>::a'.
I can't use "template<> A B<int>::a = something;" form (which would help)
because I have only empty ctor (like in the case of map).
