Hi,
with the current git tree (revision 0aec2aac), I'm running into
problems with an infinite loop in xdisp.c which I believe to be fixed
by this patch, which is reasonably obvious:
diff --git a/src/xdisp.c b/src/xdisp.c
index e45cb87..7b221d4 100644
--- a/src/xdisp.c
+++ b/src/xdisp.c
@@ -4221,6 +4221,8 @@ handle_invisible_prop (struct it *it)
if (invis == 2)
display_ellipsis_p = true;
}
+
+ charpos = end_charpos;
}
while (invis != 0 && endpos < len);
in this loop:
do
{
end_charpos = Fnext_single_property_change (charpos, Qinvisible,
it->string, limit);
if (INTEGERP (end_charpos))
{
endpos = XFASTINT (end_charpos);
charpos = end_charpos;
prop = Fget_text_property (end_charpos, Qinvisible, it->string);
invis = TEXT_PROP_MEANS_INVISIBLE (prop);
if (invis == 2)
display_ellipsis_p = true;
}
}
while (invis != 0 && endpos < len);
Without the patch, we keep calling Fnext_property_change with the same
arguments and expecting a different result, which obviously never
happens. In fact it seems to me we only need one of charpos and
end_charpos as the code currently stands, anyway. However, charpos =
f(..., charpos, ...) might cause confusion.
I can provide more detail if necessary, but as I said, it's a fairly
obvious bug.
