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
sorry for the noise, seems i misread something!
