The code in OIN::optimize_inner() has this call

   calc_group_buffer(this, group_list)

the call is however bypassed when the optimizer figures out that the JOIN
has "Impossible WHERE".

If we attempt to calculate the value of a window function afterwards,
we will get a crash when trying to create a temporary table.

So, put a call to calc_group_buffer() here as well. It's a bit surprising
that all these steps are done for a query that will produce zero rows
but we are just following the approach taken by the fix for mdev-11999
here.
