Grep currently supports only PCRE.  I'd be surprised if it worked with PCRE2.

My test was with PCRE 8.35 with Debian and Ubuntu patches (I'm up-to-date with 
Ubuntu 15.10 on x86-64).  Yours was with 8.37, I assume with no patches. 
Perhaps if I find the time I can try building PCRE 8.37 on Ubuntu 15.10 and see 
whether it exhibits the bug, but to be honest I was hoping someone else could 
debug this.  Perhaps you can try it with 8.35 on linuxfromscratch?

I assume you're doing your test on x86-64?  (Sorry, don't recall.)
