Any ideas what could be going wrong?

It appears you've run afoul of glibc bug#18781.

Yeowch.  If I'm right, that's a serious glibc bug that will break a lot 
of programs, not just grep.  I don't offhand see a way to work around it 
easily on Gnulib.

The bug was introduced on 2015-06-04 and fixed on 2015-08-10 in glibc.
