--- Comment #43 from Norman Yarvin <yarvin at yarchive.net> ---
Well, whatever that last crash I reported was, it's now fixed in the current
git head.  (But not before making it out into 2.99.907, which is why I tried
the current git head.)  I can be pretty confident about this, since those
crashes happened so fast, whereas the current version has been stable for a
couple of days.  But I still am getting the window border corruption when I
turn off FORCE_FULL_SYNC.  As for whether this might be a manifestation of bug
55500, I doubt it.  I wasn't getting any of the character corruption reported
in that bug, back when it was first reported (nor even later when I first
reported this bug); then sometime starting a few months ago I started getting a
bit of it; then the git head as of a couple of days ago increased it to where
it became bothersome; and now the current git head seems to have fixed it
completely.  And I was getting the character corruption even with
FORCE_FULL_SYNC, whereas the window border corruption has always disappeared
with it.

In any case, this seems to me to be three different bugs: the 55500 one, the
fast crash one, and this one, the one I've been seeing all along.  Of course,
given that I'm the only one reporting this one, one might wonder whether
there's just something wrong with my hardware: some circuit that just didn't
get built right, and results in occasional glitches when stressed by the new
SNA code.  My guess would be that it's my configuration that is odd, not my
hardware, but either way, this is about the hairiest sort of debugging there
is, and if it is to benefit only one person it can't be worth doing.  So I'm
not going to re-open it...
