Gijs> So, if I load them one by one, it seems to be the ✓ that trips up
Gijs> Gnus. It was already the 2nd.
Gijs> I then restarted emacs-snapshot-x in the gdb, and tested the remaining
Gijs> 6, adding them one-by-one, and then, lastly also evaluated the 1st,
Gijs> gnus-expirable-mark.
Gijs> At this point, I drafted an email to you, and saved it.
Gijs> So, when I load 1 *and* 3 - 8, Gnus seems to work just fine. I'm testing
Gijs> this by going into a mail group, selecting the first message in a email
Gijs> back and forth conversation , and then entering the replies one by one.
Gijs> But, once I load the tickmark, Gnus trips up. I can enter the group,
Gijs> scroll to the first message, and select this. I can't select any message
Gijs> below that point (using either the arrow or C-n): point will jump back
Gijs> to the random message. And, all the messages in the thread turn 'green',
Gijs> the point jumps to a random (unsure if it is random) earlier message in
Gijs> the Group.
Gijs> What's more, when I then 'reset' the gnus-read-mark to R, exit the
Gijs> group, go into the draft folder, and want to finish a draft of this
Gijs> email to you, emacs-snapshot seems to recieve SIGABRT; the screen
Gijs> becomes unresponsive and I can see the (gdb) prompt.
Gijs> bt is attached
Gijs> Does this narrow things down?
Yes, thanks. I can get a crash with that recipe.
Eli, the abort in Gijs' backtrace is coming from
if (ch < 0 || ch > MAX_CHAR)
emacs_abort ();
in bidi.c
but when I run his recipe I get:
