Thanks for the report and sorry about the delay.
I'm guessing that is due to your use of an older version of gcc.
Can you still reproduce that problem using grep-2.21? If so, can you
try a newer version of gcc?

Which version of gcc are you using?

I do not use CentOS anymore.
Now I am using Fedora 21 and I cannot reproduce it on Fedora 21.
You can close this bug as for me.

Thanks,
