`tradcpp0' segfaults on nul bytes.
When Debian switched to gcc-3.2 my applications' X resources
stopped being honored. It turns out that `xrdb' processes
its input with `cpp -traditional' and I had a useless nul byte
at the end of my .Xresources.
I can reproduce this segfault with 3.1. It works fine with 2.95.
>How-To-Repeat:
Create a file containing a nul byte, and run it through
the traditional preproc.
% echo '\0' > bar
% od -c bar
0000000 \0 \n
0000002
~ % cpp bar
# 1 "bar"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "bar"
bar:1:1: warning: null character(s) ignored
~ % cpp -traditional bar
cpp: Internal error: Segmentation fault (program tradcpp0)

Jakub, this is the second report of this regression you introduced.
Do you intend to fix it?
Neil.
