--- Comment #7 from Jason Vas Dias <jason.vas.dias at gmail dot com> --- And there is no workaround, really - one cannot initialize a C++ class object member of a static thread_local C++ template class object member in one place, outside the class, and use that same object in a non-static member function of the template class, and instantiate another instance of the same template (with different parameters) in the same translation unit - re-declaration in each using member function allows compilation to succeed, but just hides the static class member, so you can't actually use the single initialized static member in a non-static member function. So you HAVE to access thread_local static class members ONLY through pointers ? I will try this.
