This bug report will be sent to the XEmacs Development Team,
not to your local site managers!!
Please write in English, because the XEmacs maintainers do not have
translators to read other languages for them.
In XEmacs 21.1 "20 Minutes to Nikko" [Lucid] (i386-pc-win32) of Fri May 14 1999 on ZJ75T
configured using `configure UNKNOWN'
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
Moving mouse in balloon-help crashes XEmacs-21.2-b15. This bug has
been around for a long time. Now I decided to look into it.
D:\export\home\tmp\21.2\xemacs\src>xemacs
Fatal error: assertion failed, file ..\src\redisplay.c, line 6658, abort()
To reproduce it, I need to load gnus and display-time.
Moving mouse to mail envelope in mode-line brings up another XEmacs
frame as a side-effect on MS-Windows.
Moving the mouse around in this new frame will crash XEmacs with above
assertion.
Here's the source with the call to abort():
start_elt = point_in_line_start_cache (w, cur_start, 0);
if (start_elt == -1)
==> abort (); /* this had better never happen */
while (1)
