[PATCH v2 1/3] midx: fix broken free() in close_midx()

[Derrick Stolee via GitGitGadget]

From: Derrick Stolee <dsto...@microsoft.com>

When closing a multi-pack-index, we intend to close each pack-file
and free the struct packed_git that represents it. However, this
line was previously freeing the array of pointers, not the
pointer itself. This leads to a double-free issue.
