A specialization of a static member included from multiple cpp files generates
multiple definition errors. Example follows, requires 3 files (header and 2
.cpp files which include it). Tested on linux with gcc 4.2.3 (Ubuntu
4.2.3-2ubuntu7) and osx with gcc 4.0.1 (Apple Inc. build 5465).
Compile with: g++ -Wall -g -o a a.cpp b.cpp
// a.h
struct a{};
template <typename T>
struct t
{
static int const v;
};
template <> int const t<a>::v = 42;
// a.cpp
#include "a.h"
// b.cpp
#include "a.h"
