Description tbartdev 2011-07-04 22:18:16 UTC

Basically, these bug reports say it all:
http://savannah.gnu.org/bugs/?29820
http://sources.redhat.com/bugzilla/show_bug.cgi?id=11561


tbart@blackknight ~ $ /bin/echo achb | grep 'a[[.ch.]]b'
grep: Invalid collation character

the suggested workaround:
tbart@blackknight ~ $ /bin/echo achb | grep 'a[[.c-h.]]b'
grep: Invalid collation character

also does not work.

man 7 regex clearly states this should work. (Line 64)

My system is current, and I'm using de_AT.UTF-8, but it happens with POSIX and C as well.

Seems to be a known bug in glibc that's already fixed. Is our glibc too old or is this some sort of regression?

What in-tree version will have the upstream fix? 

2.14.1-r3 does not seem to have it (that's the latest stable and installed on my system..)

there is no "upstream fix", so i don't know what you're referring to
