bug#5730: 23.1.94; Emacs crash running gnus on Windows

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

This crash is repeatable but triggering it can take a lot of use.
I built emacs-21.1.94 from the pretest tarball using MinGW gcc
and image DLLs from the GnuWin32 project (the DLLs are copied into
the emacs/bin directory). The crashes occur on emacs built on two
different machines running WinXP SP3, using the same startup files
(.emacs.d/* and .gnus).

To recreate the crash, start gnus with 'M-x gnus' and then open and
browse through newsgroups. The crash always occurs after opening the
summary buffer for a group from the *Group* buffer. The crash occurs
after the *Summary* buffer is visible and seems to be fully displayed.


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
c:/emacs/emacs-23.1.94/etc/DEBUG.

With charpos=0x5ad in the trace above, I ran gnus again and opened the summary
buffer for the same group. Doing 'M-x goto-char 1453' puts point on '...' in the
summary buffer, and 'M-x describe char' shows:

        character: C-j (10, #o12, #xa)
preferred charset: ascii (ASCII (ISO646 IRV))
       code point: 0x0A
           syntax:      which means: whitespace
      buffer code: #x0A
        file code: #x0A (encoded by coding system utf-8-dos)
          display: by this font (glyph code)
