it's nesting that counts, not whether they all match.  i still find it
difficult to believe that your document has 255 _real_ grouping
levels:

i didn't suppose there was; i was just demonstrating that there's no
traceback even though there are 255 nested functional calls.

however, it might be useful to know what the error message _does_ tell
you.

apart from the file itself ;-)

it's possible that there's a bug in that, i suppose, but it could be
in anything.  perhaps inputenc from the 2003/12/01 latex could
supplant your need for ucs.sty, and perhaps thereby eliminate one file
from your checks.
