As Peff reported [1], the refactored can_all_from_reach_with_flags() method does not properly peel tags. Since the helper method can_all_from_reach() and code in t/helper/test-reach.c all peel tags before getting to this method, it is not super-simple to create a test that demonstrates this.
I modified t/helper/test-reach.c to allow calling can_all_from_reach_with_flags() directly, and added a test in t6600-test-reach.sh that demonstrates the segfault without the fix. The fix in commit-reach.c is Peff's fix verbatim.
