I wasn't able to reproduce the bug on my system, even with the
version 2.4.2, which is quite old.

What system do you use?
What locales do you use (command locale will tell you)?

I guess that you use an early version of GNU libc version 2.x, which
probably contains the bug.  Try recompiling grep, with
        ./configure --with-included-regex

Hope this helps,
