Well thought-out.  Thanks.

[PATCH 2/5] test-lib: turn on ASan abort_on_error by default

[Jeff King]

By default, ASan will exit with code 1 when it sees an
error. This means we'll notice a problem when we expected
git to succeed, but not in a test_must_fail block.

Let's ask it to actually raise SIGABRT instead. That will
give us a signal death that test_must_fail will notice. As a
bonus, it may also leave a coredump, which can be handy for
digging into a failure.
