[gnutls-devel] GnuTLS | Tests: Memory leak in pkcs11/long-label.c (missing gnutls_free ) (#1799)

[Read-only notification of GnuTLS library development activities]

Conor Tull created an issue: https://gitlab.com/gnutls/gnutls/-/issues/1799



In `tests/pkcs11/long-label.c`, the test iterates through tokens using `gnutls_pkcs11_token_get_url()`.

According to the documentation (https://man7.org/linux/man-pages/man3/gnutls_pkcs11_token_get_url.3.html) , `gnutls_pkcs11_token_get_url` allocates memory for the `url` string which must be released using **`gnutls_free()`**.

Currently, the loop checks the content and continues to the next iteration if it doesn't match the target, overwriting the pointer and leaking the memory allocated in the previous iteration.
