Bug#736198: undeterministic output when running egrep repeatedly with the same input
Package: grep
Version: 2.15-2
File: /bin/egrep
Severity: grave
User: debian-...@lists.debian.org
Usertags: kfreebsd
The following command is supposed to yield a match every time (i.e.
egrep should filter the line containing MNT_RDONLY from sys/mount.h).
However, approximately 20% of the time it doesn't. This is the result
of 100 attempts:
$ for i in $(seq 100) ; do egrep
'^#[[:space:]]*define[[:space:]]+MNT_[A-Z]+[[:space:]]+0x[0-9]+[[:space:]]*'
/usr/src/kfreebsd-headers-10.0-1/sys/sys/mount.h | grep MNT_RDONLY | head -n 1
; done | wc -l
72
This is a regression from wheezy (not sure if due to grep itself or
some libc issue).
