Example pair:\n\n  NEEDLE:   6 x x 4 6\n  HAYSTACK: 4 6 x x 4\n\nWe find the subsequence 6 4, but the needle is not yet at end (missing\n6) while the haystack is moved past the end:\n\n  NEEDLE:   6 x x 4 6\n                    ^\n  HAYSTACK: 4 6 x x 4\n                      ^\n\nIf the haystack (super) is exhausted before the needle (sub) we know\nit isn\u0027t a proper subsequence, so this is the correct behaviour.\n\nThis example was in the testsuite and caught by ASAN.\n\n\tPR gcov-profile/127038\n\ngcc/ChangeLog:\n\n\t* gcov.cc (tombstone_subsequence_p): Guard iterator\n\tdereference.\n",
