Hi,

just running 'make check' with glibc-2.28 on grep git master results in:
...
XPASS: backref-alt
...
+ grep -E 'b|(.)b|\1|b' in
grep: Invalid back reference
+ status=2
+ test 2 -eq 2
+ grep -E '0|()0|\1|0' in
grep: Invalid back reference
+ status=2
+ test 2 -eq 2
+ Exit 0
...

From the inline comment:
# The backslash-alt test fails for glibc, which needs to be fixed.
# FIXME-2015: Remove this once the glibc bug is fixed.
XFAIL_TESTS += backref-alt

so it has been probably fixed in glibc and the test should be
removed

thanks & regards

Jaroslav
