Subject: 24.3.50; GC crashes
Date: Thu, 10 Oct 2013 12:28:19 -0400

Over the past few weeks, since updating, I have had several crashes in
mark_object.  The crashes started when I updated somewhere between Sep
17 and Sep 22.  (I don't know how to tell more precisely when that
was.)

I did another update a week ago, hoping the problem would go away,
but yesterday I got another crash of the same sort.

My previous update had been around Aug 18; the crashes did not
happen in that version.

mark_object is reached about 3 levels down from mark_memory.
Thus, I could not easily tell much about what data structure it was.
If it is useful, I will try harder to get more info.

Richard, could you please establish the exact bzr revisions that you
had after the update "around Aug 18" and after the update in
September?  This could help us find the relevant changes.  Below I
explain how to find out these facts.

In your ~/.bzr.log file, you should see a line like this announcing
each "bzr update" command:

  Sat 2014-03-22 10:32:23 +0200
  0.047  bazaar version: 2.6b1
  0.047  bzr arguments: [u'up']

If you actually type the full "update" command, instead of the short
"up", the last line will say this instead:

  0.047  bzr arguments: [u'update']

In any case, the first line shows the date of the update command.  One
of the last lines in the log related to this command will look like
this:

  [ 5068] 2014-03-22 10:32:45.552 INFO: Updated to revision 116839 of branch bzr+ssh://eliz <at> bzr.savannah.gnu.org/emacs/trunk

(with "rms" instead of "eliz" in your case).  This shows the revision
to which you updated your tree.

Please find the 2 updates on or around the dates you mentioned, and
tell which revisions did you get in each update.

Thanks.
