[Bug c++/20350] [4.0/4.1 Regression] extern template and struct initializer and specification for a static variable

["carlo at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Additional Comments From carlo at gcc dot gnu dot org  2005-05-31 02:33 -------
If you remove the 'extern', the compiler still crashes:

struct a { int i, j; };
template <int i> struct mutex_tct { static a S_mutex; };
template <int i> a mutex_tct<i>::S_mutex = {0,1};
template <> a mutex_tct<0>::S_mutex;
template <> a mutex_tct<0>::S_mutex = {0,1};
void g() { mutex_tct<0>::S_mutex.i = 0; }
