Thank you for the report. I confirm that it affects grep-2.21 with this: $ echo axa |/p/p/grep-2.21/bin/grep -E '^x|x$' axa However, it appears to be fixed in the version built from the latest sources, yet there is no mention in NEWS. The actual bug was introduced in v2.18-85-g2c94326, so first appeared in the grep-2.19 release. I will track down the commit that fixed it, add a test if required and update NEWS accordingly. With this, I will prioritize making a new release soon.
