there should definitely be no overprint!

when you write in Arabic you fill a box (from the R to the L) and then place the left border of that box on the current point. Having a result equivalent to the use of \llap makes no sense.

Hi,

In the process of looking into it now, I did find some
unreliability in te i386 executable, which possibly stems
from the same bug as your crash.

Here is something weird: 'my' bug was a problem that happened
only in \pdfoutput=1 mode, and it was very easy to fix. Eythan,
if you were testing in pdf mode, this is likely the cause
of the crashes on amd64, and the latest trunk will fix it.
If you had crashes in dvi mode, my fix will do nothing for you.

I did run into something different that now needs to be resolved:

The pdf bidi output internals are quite different from the dvi
ones, and I now get the to-be-expected output "This andtaht"
(no overprint), but only in pdf mode. In dvi mode, there is
still overprint, as in Aleph.

This confuses me a bit: I am now not sure which of the two
outputs is 'officially' wrong. CC to Yannis, hoping he can tell
me whether the dvi overprint is a bug or intended behaviour
(I have attached the tex input and a pdf generated by Aleph).

Best wishes,
Taco
