+Subject: [PATCH] fetcher/curl: Fix invalid memory access in finalize()
+
+Reorder cleanup functions so that curl_multi_cleanup() runs before
+self->sockets is destroyed. This avoids an assert and invalid memory
+access in sock_cb where self->sockets is dereferenced during
+curl_multi_cleanup().
+
+Closes: https://github.com/ostreedev/ostree/issues/1331
+
+Closes: #1332
