[second try, first was blocked by automated, broken by design,
anti spam]

template <class T>
struct bar
{
   bar() {}
};

extern template class bar<int>;

static void f()
{
   bar<int> b;
}

struct foo {
   foo();
};

namespace {
   foo option;
}

this use bar ctor name to mangle option.
00000000 B _ZN25_GLOBAL__N__ZN3barIiEC1Ev6optionE

removing the extern template ... I got:
00000000 B _ZN36_GLOBAL__N_tmp30.i_6AAA976C_991AFCF76optionE

it look like compiler is confused by the extern template
and think the definition of bar() ctor can't be seen
in another translation unit so it's valid to use bar name
to uniquify option mangled name.
