Subject: [Bug preprocessor/14438] New: -E of #pragma poison has negative line number
X-Bugzilla-Reason: CC
X-SW-Source: 2004-03/txt/msg00652.txt.bz2
List-Id: <gcc-bugs.sourceware.org>

A i686-pc-linux-gnu compiler built from 
  gcc-3.4-20040303.tar.bz2
exhibits this:

echo "#pragma GCC poison foo" > _dummy.c
gcc -E -nostdinc _dummy.c
  # 1 "_dummy.c"
  # 1 "<built-in>"
  # 1 "<command line>"
  # 1 "_dummy.c"       
  # 4294967218 "_dummy.c"

Umm, ah, line number 4294967218 ? This bug was brought to my attention by GAS,
when it said:
   line numbers must be positive; line number -15 rejected

The bug is in GCC-3.3.2 but isn't in 3.3.1.
