Hi,
I've posted this to pdftex-devel:

Hi,
This turned out to be something completely different from what
I thought initially, and does not seem related to a font number
limit at all ?
My current analysis is that the internal base font defined in the
vf file is not initialized yet (so pdf_font_size[f] is still
zero) at the moment output_one_char() is called on it.
I am surprised because if that really is the problem, should
it not have happened earlier and more often?
The attached patch makes the test document run without error
on my machine. However, I am not sure whether this fixes the
problem or just makes the message disappear while still generating
wrong output.
The important line is the 'if font_used[f]' test, the other change
is just to avoid confusion (do_vf_packet used to assign to its 'f'
argument).
Best,
Taco

Problem now is that latex and dvipdfmx work, but pdflatex doesn't.
And the PDF documents in all other languages are made with pdflatex.
Strange thing as well is that it worked before with CJK v4.5.2.
Apparently, you've found a fatal bug in pdftex. I was able to reduce
it to the attached document. Using the TeXLive SVN from today (which
contains pdfeTeX 3.141592-1.30.4-2.2), the first run of
pdflatex zzzz.tex
works fine, but a second run crashes with
! pdfTeX error (arithmetic): divided by zero.
This is on a GNU/Linux box, BTW.
Hmm, your example file works on my computer though.
But the error you get is exactly the same that I get with
reference.zh-tw.tex.
I tried running latex first, and then pdflatex, and it only produces
the following warning:

% end
Nothing serious. Using pdflatex on your zzzz.tex file doesn't fail on
my distribution, and the resulting PDF works.
Running pdflatex twice (after having deleted all the files except
*.tex) works as well.
My system: teTeX3 from Debian/unstable GNU/Linux.
$ latex --version
pdfeTeX using libpoppler 3.141592-1.21a-2.2 (Web2C 7.5.4)
kpathsea version 3.5.4
Is it because I'm using an older version of poppler (0.4.5)?
I'll contact the Debian TeX maintainers to see whether Debian TeXlive
is unaffected as well when pdflatex'ing your zzzz.tex file.
