Assertion failure in redisplay code whilst displaying MIME
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 21.0 "Pyrenean63" [Lucid] (i686-pc-cygwin32) of Thu Feb 18
1999 on ps02235 configured using `configure -with-png -with-xpm
--site-includes=/usr/local/include'
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
In VM, if I middle-click a MIME message or message digest object I get
an assertion failure in the scrolling/redisplay caching code.
Line 577 in indent.c:
elt = point_in_line_start_cache (w, orig, (vtarget < 0
? -vtarget
: vtarget));
/* #### This assertion must be true before the if statements are hit
but may possibly be wrong after the call to
point_in_line_start_cache if orig is outside of the visible
region of the buffer. Handle this. */
=> assert (elt >= 0);
I don't grok the redisplay code, so its not immediately obvious what's
going on here.
