This is probably because of something I said, but this does not look
correct. The `die()` would typically print "(null)" or segfault. If the
`die()` means we don't free `graph_name`, that should be fine.
You're still leaking `graph` here (possibly nothing this patch should
worry about) and in `graph_verify()`. UNLEAK-ing it immediately before
calling `verify_commit_graph()` should be ok. I also think punting on
this UNLEAK-business entirely would be ok; I was just a bit surprised to
see one variable getting freed and the other one ignored.
