[pdftex] segfault when not using a format file

[Thomas Esser]

Hm... It does not work. Maybe, this should be fixed?

$ cat rr.tex
\pdfoutput=1
\pdfoptionpdfminorversion=4
\catcode`\{=1
\catcode`\}=2
\pdfximage{sample2e.pdf}
\setbox0=\hbox{\pdfrefximage\pdflastximage}%
\pdfpagewidth=\wd0
\pdfpageheight=\ht0
\shipout\box0
\end

This works ok:

$ pdftex rr
This is pdfTeX, Version 3.14159-1.11a-beta-20030615 (Web2C 7.5.2)
...
nts/type1/bluesky/cm/cmr17.pfb>
Output written on rr.pdf (1 page, 57830 bytes).
Transcript written on rr.log.

It even works with an "empty" format file:

$ pdftex -ini /dev/null \\dump
...
Transcript written on null.log.

$ pdftex \&null rr
...
Output written on rr.pdf (1 page, 57830 bytes).
Transcript written on rr.log.

Running pdftex -ini rr does not work:

$ gdb pdftex
GNU gdb 5.3
...
(gdb) run -ini rr
