Well, I'm not.  ;-)

In fact I have no idea about the structure of DVI files at all, but I'm
willing to learn.

All right, so it's a stack for any sort of data.

There's a problem there, I'm afraid.  The failing xdv files all contain
some customer's personal data, so I cannot provide them, sorry.  I have
not been able to reproduce the problem in a simple test case, at least
not yet.  I hope that the help I'm getting from you and others leads me
closer to what's actually causing the problem.

Somebody else suggested the issue might be related to nested boxes.  As
I do have quite a lot of those, I'm hopeful that this might be the right
track.  What do you think?

Yes, I have successfully built texlive 2008 from sources yesterday
evening, but it's not quite behaving like the binary distribution yet.

I'll investigate and let you know if setting DVI_STACK_DEPTH_MAX to 4096
made the issue go away.  If it did not I think I can be sure there's a
problem with my LaTeX code.

Thanks a lot,
have fun
