--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This has nothing to do with thread_local. That is removing static thread_local
still causes it to produce an error.
Here is a more reduced testcase:
template <typename T>
struct wrapper final
{
T value;
template <typename ...Args>
wrapper(Args &&...args)
: value(args...)
{
}
};
struct non_copyable
{
non_copyable(const non_copyable &) = delete;
non_copyable();
~non_copyable();
};
template <typename T>
class thread_local_variable final
{
private:
wrapper<T> *pointer;
public:
template <typename ...Args>
thread_local_variable(Args &&...args)
{
wrapper<T> v(args...);
pointer = &v;
}
T &get()
{
return pointer->value;
}
};
non_copyable &fn()
{
thread_local_variable<non_copyable> v;
return v.get();
}
--- CUT ----
args here is {}. I suspect an empty arguments it not being treated correctly.
