PDFTEX uses an additional map file. Is that set up ok? Normally TeX only
uses tfm data, no vf data, but pdftex does, because it has to include
the fonts. (BTW, I never used virtual fonts myself.)

Also, if the command line is
	tex --progname=context \&context file
things will work.

To be precise, I've made one patch available which should solve the
problem of tex dumping core during the undump.  While investigating
the bug I've seen some other, halfway related, problems which will be
addressed in web2c 7.3.  I don't expect to release patches for those
problems.

Hi all,

concerning TeX/eTeX of teTeX 0.9-981012 Olaf Weber
<olaf@infovore.xs4all.nl> found the reason for this.

In texmf.cnf, there is:
  max_strings.context = 55000
  max_strings = 15000             % max number of strings

using 'tex --ini --fmt=context cont-de' the first line is read, but when
calling
tex \& context  the second line is read, and since cont-de needs 18053
strings, it segment faults.

If context is linked to tex (ln -s tex context) and tex is called
'context' then it doesn't happen.

(Since in teTeX cont-* is soft linked to pdftex, which presently doesn't
work, I used (e)TeX and failed.)

Olaf Weber will provide three patches to solve this bug/problem. See
teTeX-pretest mailing list.

ConTeXt + teTeX 0.9-981012/Linux: SegFault

[Tobias Burnus]

Hi teTeXers and contexters,

I just installed (from scratch) teTeX 0.9-981012 unter Linux 2.0.35/libc5/gcc 2.7.2.1
unsing 'make world'
I use the updated ConTeXt version from http://frambach.eco.rug.nl/pragma/zipped/

Using the buggy teTeX PDFTeX (which compiled w/o any problems) I get:

strace cont-de file:

(there is no cm*.vf according to 'locate')
