Hello!
(Please, CC me with replies.)
After the latest CVE fix I'm getting an assertion failure in tests 
(below). I reproduce that both on latest master (846e7eee8) or with 2.21 
with patch 83a95bd8c8 applied (2.21 itself is OK).

XFAIL: triple-backref
=====================

grep: regexec.c:1401: pop_fail_stack: Assertion `num >= 0' failed.
./triple-backref: line 32:  8135 Aborted                 grep -E
