I managed to reduce this case further. Not entirely sure if it really managed
to pinpoint the same thing or if it diverged into something else, but this
snippet produces a different set of defined/undefined symbols before and after
this change.
```c++
namespace a {
typedef int b;
}
class c;
class d {
template <typename = int> void e(c *, int, int);
};
class f {
public:
static bool g;
};
template <typename> struct h {
template <typename, typename... i> static bool j(i...);
};
template <> template <typename, typename... i> bool h<d>::j(i...) {
f::g ? h<int>::j<int> : 0;
}
template <> template <typename, typename... i> bool h<int>::j(i...) {}
template void d::e(c *, a::b, int);
template <typename> void d::e(c *, int, int) { f::g ? h<int>::j<int>() : 0; }
```
