Hi Derek,

Thanks for the report.
I get the expected (not buggy) results when
using the latest test release:

 ftp://alpha.gnu.org/gnu/fetish/coreutils-4.5.3.tar.gz

 $ expr 'abc
 > xxxxx
 > def' : 'abc
 > .*
 > def'
 13
 $ expr --vers
 expr (GNU coreutils) 4.5.3

So I guess you should encourage RH to upgrade.

Nope.  That doesn't appear to be the problem:

address@hidden coreutils-4.5.3]$ src/expr 'abc
xxxxx
def' : 'abc
> .*
> def'
0
address@hidden coreutils-4.5.3]$ src/expr --version
expr (GNU coreutils) 4.5.3

RedHat is blaming glibc version 2.2.93. What version of glibc do you have installed?

I ask because I'm trying to figure out if this is worth the hassle of upgrading glibc without RedHat's help or if I should be reporting this problem to the glibc mailing list.
