Indeed. Our mails crossed.

To fix just this bug (as opposed to the other Gnulib-related bugs that 
may be lurking) try applying the attached Gnulib patch to a grep 3.11 
tarball.

Closing the debbugs.gnu.org bug report, as the bug has been fixed upstream.

Thanks for reporting that.
I've just pushed the following, adding a NEWS entry for the 3.11 bug and a test.
