I tested this, and it works for me.  (I used LC_ALL, to be sure that
all locale categories are consistent.)

The problem is probably in GNU libc.  I use glibc-2.3.3-27 on a Red
Hat derived system (Fedore, Whitebox, ???) and glibc-2.3.2 on a ROCK
GNU/Linux system, and it works for me.

If you use an older version, an upgrade should help.

If you are not brave enough to upgrade libc, you can try recompiling
grep, using ./configure --with-included-regex, it might help.
(It would help if the bug is in regex code, not in other parts of libc.)

Good luck,
