Package: grep
Version: 2.5.3~dfsg-2
Severity: grave
Justification: renders package unusable
With etch's grep:
% time LC_ALL=C grep -v '^ ' short | LC_ALL=C grep : >| /dev/null
LC_ALL=C grep --color=tty -d skip -v '^ ' short 0,00s user 0,00s system
89% cpu 0,004 total
LC_ALL=C grep --color=tty -d skip : >| /dev/null 0,00s user 0,00s system
0% cpu 0,004 total
% time grep -v '^ ' short | grep : >| /dev/null
grep --color=tty -d skip -v '^ ' short 0,00s user 0,00s system 93% cpu
0,009 total
grep --color=tty -d skip : >| /dev/null 0,00s user 0,00s system 50% cpu
0,008 total
With the one in unstable:
% LC_ALL=C grep -v '^ ' short | LC_ALL=C grep : >| /dev/null
LC_ALL=C grep --color=tty -d skip -v '^ ' short 0,00s user 0,00s system
87% cpu 0,005 total
LC_ALL=C grep --color=tty -d skip : >| /dev/null 0,00s user 0,00s system
0% cpu 0,004 total
% time grep -v '^ ' short | grep : >| /dev/null
grep --color=tty -d skip -v '^ ' short 10,97s user 0,05s system 99% cpu
11,101 total
grep --color=tty -d skip : >| /dev/null 0,00s user 0,00s system 0% cpu
11,100 total
So it seems that multibyte support is completely broken for some reason.
This renders grep compltely unsuitable for use in code like the kernel,
which is what it's made for in the first place.
