I think it's a case of memory corruption and doesn't really have much to
do with bidi code. But I'm not progressing very fast: it's somewhat
deterministic but it is influenced by elements I'm not aware of, so it's
pretty nasty.

It's a machine that's not reachable from the internet and is off most of
the time. I haven't yet managed to reproduce it on another machine.
I'll let you know when I'm making progress,
Thanks,
