A vector used as a ring buffer (so we don't "start" at 0), containing
integers or symbols denoting keys pressed or lists recording events like
switch-frame or commands invoked. Decoding that all at once would be handy,
since I can't use "C-h l" on a core file.

I've got one in the works, now, but it's got some glitches left to work
out. And I'm more interested in getting xbacktrace working again.

Yes

Anyway, do you have any explanation for why this started happening

I switched one week ago to emacs-25.0.92 from emacs-25.0.90, which I'd been
running since early or mid February.  I didn't see this problem in .90,
though a couple of assertion failures in find_last_row_displaying_text
prompted me to pick up the newer snapshot.  Some changes I saw in the log
for .92 made me think maybe that had been addressed, so I wasn't planning
to report the assertion failure unless I saw it again in the newer snapshot.
