When using the following command, *most* of the time I get a
Segmentation fault (10 out of 16 times):
€ cat grepTxt | grep -P 'b(?:(?!tom).)+'
Segmentation fault (core dumped)
This happens with the grep version that came with my Linux installation:
€ grep -V
grep (GNU grep) 2.16
I am on:
NAME="Ubuntu"
VERSION="14.04.1 LTS, Trusty Tahr"
But also compiled grep from sources
(http://ftp.gnu.org/gnu/grep/grep-2.21.tar.xz) with the same problem.
libpcre3:amd64; libpcre3:i386; libpcre3-dev:amd64; libpcrecpp0:amd64 are
all 1:8.31-2ubuntu2
I tried to reduce the regex and the text as much as possible to still
reproduce the issue most of the time, unfortunately the text is still
16893 bytes long. As I don't know if it is OK to attach such a long
file, I put it on pastebin, but will expire in a month.

Please advise.
Kind regards,
