Yes I think it's a dup. That issue also has a reference to the core issue that
affects this trait.

Are we sure this is a non pod due to volatile with packed?  Does removing the
packed attribute still cause GCC to think the MyTimeDate is a non-pod?

Is this an exact Dup of PR66268?

I think that the underlying issue is that in the front-end the code
implementing the traits, in particular, say, trivial_type_p, isn't directly
used elsewhere (should double check this, but I'm pretty sure), thus an issue
like this one may show up in the library first, which seems a bit weird, at
first. Conversely, it would be very interesting if we had a pure C++ testcase
on which the front-end misbehaves exactly because it has the wrong concept of
POD-ness wrt volatile. Do we have one?

Uhm, then I understand nobody raised a library issue so far? Of course our use
of __is_pos is just an implementation detail. Weird.

Not really a library issue, since we just use the compiler intrinsic:

  template
struct is_pod
: public integral_constant
{ };
