Thanks for your contribution.

>This fixes the problem for me.

Unfortunately, this does not fix the your reported problem in my
environment.  When displaying your sample TeX code with patched xdvi,
it says as follows:

% xdvi sample.dvi
xdvi.bin 22.84.8 j1.22 (Xaw toolkit): events.c:4144: Shouldn't happen: 
Segmentation fault - trying to clean up and aborting ...
xdvi: xdvi.bin terminated abnormally: 6

The debian package which including both new upstream and your patch is
put at:

http://namazu.org/~tsuchiya/debian/xdvik-ja/

Can you try it?

It is included in the localization patch distributed at
.

If the rotated hline occurs early in the dvi file, then it is possible
that globals.gc.rule is null, hence the SEGV.

You need to add the following into dvi-draw.c:set_rotated_rule before
the XFillPolygon call:

#if COLOR
if (fg_active != fg_current)
do_color_change();
#endif

This brings it inline with put_rule.

Ok. I see the same error as you on my sample, however my original
problem was with a rotated table in a much larger document, and in that
case it works without error. I will try and look into it later. 

Who wrote the rotated  hline stuff? It's not in upstream.

Bug#277335: fix

[Robert Hart]

This bug is debian specific and due to the patched dvi-draw.c

specifically in set_rotated_rule(), the line

if (--globals.ev.ctr == 0) read_events(False);

should be replaced by:

if (--globals.ev.ctr == 0) {
  if (read_events(EV_NOWAIT) & EV_GE_MAG_GONE) {
/*  fprintf(stderr, "longjmp1!\n"); */
longjmp(globals.ev.canit, 1);
  }
}

to be consistent with the way read_events is used elsewhere. This fixes
the problem for me.

Please can you apply this fix, the bug is very old.
