Package: grep
Version: 2.4.2-3
Severity: normal
I am running Woody on this system, but I have another one with a Sarge
/ Sid mix (Woody installation upgraded to Sarge, then added Sid to apt
sources and installed some unstable packages) where I get different
behavior from egrep.
With libc6 2.2.5-11.2:
$ egrep '[[:moo:]]' /dev/null
egrep: Invalid character class name
$ egrep '[[:print::]]' /dev/null
egrep: Invalid character class name
With libc6 2.3.1-16:
$ egrep '[[:moo:]]' /dev/null
egrep: Memory exhausted
$ egrep '[[:print::]]' /dev/null
egrep: Memory exhausted
I'm speculating that libc6 is at fault because I have the identical
version of the grep package on both systems (2.4.2-3). Also both the
error message strings are present in /lib/libc.so.6 on both boxen.
The output from strace looks (to my untrained eyes) identical on both
systems, and there's no serious memory consumption going on before the
error message is printed as far as I can tell.
Here's the libc6 dependency information from the Sid/Sarge system:
libdb1-compat 2.1.3-7
Sorry, the box is not connected to the Internet, so I can't copy &
paste very conveniently.
I was going to submit this to the libc6 maintainers, but couldn't
really make up my mind (it's not like I understand what's going on
here, although I can speculate). Obviously, feel free to reassign this
to libc6 if you think it's their problem.

I cannot reproduce this bug with libc6 2.3.5-7, and thus close it.
Please reopen it if you believe that it is not fixed.
Thanks for your report.
