Hmm. I see that set_buffer_internal() is unchanged since 21.4.22 (which
doesn't exhibit the failure).
Would point normally be in the local variable list for the buffer? I
see that there is code in set_buffer_internal() to sync the Lisp and C
values of buffer-local variables. Could that be broken?
It seemed odd to me that the old buffer's variables would get
synchronized after setting current_buffer, but moving that code to come
before setting current_buffer doesn't seem to fix anything.
