Even smaller test case
template int i struct Mutex
{
static int mutex;
};
template int i
int Mutexi::mutex = {1};
template int Mutex0::mutex;
template int Mutex0::mutex = 0;
void g()
{
Mutex0::mutex = 0;
}

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_tcti::S_mutex = {0,1};
template a mutex_tct0::S_mutex;
template a mutex_tct0::S_mutex = {0,1};
void g() { mutex_tct0::S_mutex.i = 0; }

Confirmed, reduced testcase:

template int i struct mutex_tct { static a S_mutex; };
template int i a mutex_tcti::S_mutex = {0,1};
template extern a mutex_tct0::S_mutex;
