Hi,
Machine: M1 sonoma 14.1.1
At my test I am using the shipped lib of curl, and its default used SSL,
that is:
curl 8.1.2 (x86_64-apple-darwin23.0) libcurl/8.1.2 (SecureTransport)
LibreSSL/3.3.6 zlib/1.2.12 nghttp2/1.55.1
I am getting memory leaks while running the following test:
*void* CallCurl() {
CURL *hnd;
hnd = curl_easy_init();
curl_easy_setopt(hnd, CURLOPT_URL, "https://www.google.com");
curl_easy_perform(hnd);
curl_easy_cleanup(hnd);
}
I track the leaks with macOS instruments, and I see that all leaks are from
SSL (I am using the default SSL that the shipped curl uses).
Examples for the leaks stack frames:
1.
serialize_ECPublicKey
ECDSA_do_verify_new
ossl_ecdsa_verify
EVP_DigestVerifyFinal
tls13_server_certificate_verify_recv
tls13_handshake_perform
tls13_legacy_connect
ossl_connect_common
ssl_cf_connect
cf_setup_connect
cf_hc_connect
Curl_conn_connect
multi_runsingle
curl_multi_perform
curl_easy_perform
CallCurl()
main
start
2.

Any advice?
Thx,
Moshe.
