For LFS, we do not build grep with PCRE by default.  Users are free to 
rebuild after pcre-8.42 is installed in BLFS.

On my system (x86_64, linux-4.19.8, glibc-2,28, gcc-8.2) with pcre 
installed I have )for grep-3.1):

XFAIL: triple-backref
XPASS: backref-alt

For this I get in 3.1:

# i=200; printf %0${i}0000d 0|tr 0 '(' > in; src/grep -Ef in; echo $?
Segmentation fault

For 3.1.51-e767

# i=200; printf %0${i}0000d 0|tr 0 '(' > in; src/grep -Ef in; echo $?
grep: stack overflow
