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.
