Crash in CLI tool, no security impact
[stretch] - vim <ignored> (use after free, testcase does not trigger in valgrind, delayed quickfix freeing infrastructure is entirely missing in stretch)
[jessie] - vim <ignored> (use after free, testcase does not trigger in valgrind, delayed quickfix freeing infrastructure is entirely missing in stretch and earlier)
