There was an xmalloc() for path, but I didn't see a corresponding free().
Does it happen somewhere else that I'm not expecting?

It implicitly happens in exit() in git.c:handle_internal_command()
after cmd_init_db() returns the control to it.

Ah. Naturally. :)

So if I were to write a long-lived application (such as a custom UI) that
links to libgit, and bypasses those functions to call init_db() (and other
functions) directly, all those implicit free-on-exit() turn into memory
leaks.

Correct, and there are other much larger issues to worry about.

That's why there is a separate libgit2 effort in progress.

Okay, cool! I wasn't aware of that -- I'll take a look at it. In the meantime,
are small patches for this type of issue welcome if I run across others,
or would you prefer I let them lie?

Cheers,
Ammon
