FOR-RELEASE mentiones these bugs:

    ** Investigate reported crashes in compact_small_strings.

    ** Investigate reported crashes related to using an
    invalid pointer from string_free_list.

They were reported a long time ago, before we realized it was a good
idea to copy the actual bug reports there.  They have not been
reported recently that I recall.  Does anyone recall seeing such
bugs recently?

Is there any reason to think they are fixed already?

Could someone possibly search for these bug reports,
see who reported them, etc?

I've submitted a bug report concerning compact_small_strings:

,----[ http://thread.gmane.org/gmane.emacs.pretest.bugs/3866 ]

This problem was solved later, IIRC.  I didn't see this problem in the
last months.

A different one concerning compact_small_strings was:

Kim F. Storm sent a patch and Stephen Eglen posted a different
backtrace.

With CVS of 2005-05-31, I still get occasional dumps (once/twice a
week), and they usually seem to be when I'm going to get new mail
using VM 7.17.  I am now running emacs under gdb again so the next
time I get an error, I can send a backtrace to whoever wants to see
it!  But am I the only one who sees them nowadays?

M-x emacs-version

GNU Emacs 22.0.50.1 (i686-pc-linux-gnu, GTK+ Version 2.0.6) of
2005-05-31 on notch.amtp.cam.ac.uk

I've never had such a crash, but I don't use VM.  I have the
impression VM has always been a bit odd in some ways (in particular
its approach to encoding/decoding), so it may tickle some otherwise
rare bugs.

[Emacs has been pretty solid lately for me (the main crashing problems
I used to have were the old face cache bugs, but those seem to have
been fixed).]
