Flushing or freeing a newly created dynamic window leads to NULL being passed to the wpmem functions.
Addresses part of what was reported in #6987. This allows at least to flush/free an empty dynamic window without Segfault. It's a bandaid, not a full fix, but I ran into this multiple times with some code that happens to create/flush/free empty dynamic windows so I need a fix for that at least.
