Hi Pavel,

Thanks for the report.

Using the latest test release (compiled against libc-2.3.1),
I can't reproduce that problem.  And there haven't been any
significant changes to expr.c since 2.0.15.  Would you please
see the same problem using the latest test release?

  ftp://alpha.gnu.org/gnu/fetish/coreutils-4.5.4.tar.bz2
  (coreutils is the union of fileutils, textutils, and sh-utils)

If you *do* reproduce your problem, please let me know whether
your build used lib/regex.o or not, and include the output of
running /lib/libc.so.*.
