Subject: dvips/pdftex: font / buffer overflow

There is a free christmas font Chrimbobat (www.fontmonster.co.uk). After
making a myfonts.map file, the font could be included into TeX text, e.
g. by \font \chrim chrimbob at 100pt \chrim m \bye and displayed (even
zoomed into) with xdvi.

But dvips fails:

This is dvips(k) 5.92a Copyright 2002 Radical Eye
Software (www.radicaleye.com)
' TeX output 2002.12.15:2220' -> x.ps
<texc.pro><texps.pro>. <cmr10.pfb><chrimbob.pfb>
Error: module writet1 (file chrimbob.pfb): buffer overflow [8192 bytes]

And so does pdftex:

This is pdfTeX, Version 3.14159-1.10a-beta-20021115 (Web2C 7.3.11)
(./x.tex{/usr/local/teTeX/share/texmf/pdftex/config/pdftex.cfg}
[1{/usr/local/t
eTeX/share/texmf/dvips/config/pdftex.map}{myfonts.map}]
)</usr/local/teTeX/shar
e/texmf/fonts/type1/bluesky/cm/cmr10.pfb><chrimbob.pfb
Error: pdftex (file chrimbob.pfb): buffer overflow
 ==> Fatal error occurred, the output PDF file is not finished!

Same after font conversion to .pfa.

ls -l tells:

-rw-rw-rw-    1 hahe     hahe       150415 12-04 09:06 chrimbob.pfb

Which buffer is this? Is this a web2c feature? Can the buffer be
increased?

Greetings Hartmut

This is parameter T1_BUF_SIZE = 8192 in writet1.c, in the dvipsk and
pdftexdir directories. It is hardcoded by #define. Used both by dvips
and pdftex. Increasing it to 16384 in the source allows inclusion of the
christmas font.
