This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.

(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)

With grep-2.16 I am unable to reproduce the problem any more.

grep-2.16-1.fc20 has been pushed to the Fedora 20 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 1 Jaroslav Škarvada 2014-01-09 10:46:28 UTC
The best approach to resolve this is rebase grep to 2.16.

Fixed in grep-2.16-1.el7.
