"Should" in what sense? w32_wnd_proc, the function in which this
happens, is the main window procedure for Emacs, and it runs in the
input thread, which is separate from the Lisp thread. The code which
crashes is the only one in w32_wnd_proc that references buffers,
windows, and frames, which are objects that are manipulated (and
GC'ed) by the Lisp thread.
Did I answer your question?
