[XeTeX] XeTeX error, no PDF

[Stephen Moye]

I have been using XeTeX 0.997 (on a Mac G5 DP) without any problems to speak of -- until tonight.

I typeset a file and got this error message:

This is XeTeXk, Version 3.141592-2.2-0.997 (Web2C 7.5.6)
 %&-line parsing enabled.
entering extended mode
(./Hanover-new.tex [2] [3]
Output file removed.
 )
Error 256 (driver return code) generating output;
file Hanover-new.pdf may not be valid.
Transcript written on Hanover-new.log.

This file uses a fmt file that I have regenerated. The file uses Hoefler Text. Oh, and I just upgraded to Leopard.

Other similar files are OK -- there are just a handful that show this problem.

Where do I start looking for problems?

Thanks for any help.
