diff: cleanup hash ctx in git_diff_patchid#4348
Merged

Conversation
After initializing the hash context in `git_diff_patchid`, we never proceed to call `git_hash_ctx_cleanup` on it. While this doesn't really matter on most hash implementations, this causes a memory leak on Win32 due to CNG system requiring a `malloc` call. Fix the memory leak by always calling `git_hash_ctx_cleanup` before exiting.
