To: gcc-bugs
Bug happens (at least) on RedHat 7 (gcc 3.2.3) and cygwin (gcc 3.3.1)
Bug conditions (if relaxed, the bug disappears):
1. A class contains an initialized static const variable
2. There exists an external template function which may get this variable
as a parameter
3. A class contains a virtual function that calls the template function
above with static const as a parameter
Typical output: undefined reference to <var>; undefined reference to vtable.

The code is not valid as you still need to have declaration of T::N.

ANSI C++ allows inline initialization of const static members without their
declaration (at least this was the state in Draft of 1996).

But you taking a reference to it so GCC is not going to lay down another copy of it.

The standard says that you may inline-initialize the static variable,
but you still need to _define_ it somewhere so that a memory location
is assigned to it.
