I've built 21.1.94 pretest on WinXP SP3 with MinGW gcc, and I'm seeing
a repeatable crash in gnus. Running emacs under gdb I managed to capture
a crash, with the following results:
Program received signal SIGSEGV, Segmentation fault.
0x0102ef33 in pos_visible_p (w=0x2fa6e00, charpos=0x22fa, x=0x82eef8,
y=0x82eef4, rtop=0x82ef08,
rbot=0x82ef04, rowh=0x82ef00, vpos=0x82eefc) at xdisp.c:1397
1397&& (!BUFFERP (glyph->object)
Thank you for your report.
Please let me know what other info/testing is needed to help fix this.
First, please file a bug report with this information.
I've sent a bug report (from another machine after recreating the crash).
Second, please type "bt full" and post the results.
Third, if this is an optimized build, please build Emacs without
optimizations, and when the crash happens again, please type "bt full"
and send the results.
Finally, could you tell what kind of text is at character position
(in this case, 0x22fa) with which pos_visible_p is called when it
crashes? Are there any unusual text properties there, like invisible
text, ellipsis (which stands for hidden text), or something similar?
emacs was configured on both machines with "--no-opt". I've added details of
the crash in the bug report below.

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)
uniscribe:-outline-DejaVu Sans
