Assignee: Ken Giusti
> crash in pn_tls_start() if pn_tls_config_t freed after call to pn_tls()
> -----------------------------------------------------------------------

> Key: PROTON-2851
> URL: https://issues.apache.org/jira/browse/PROTON-2851
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: proton-c-0.40.0
> Reporter: Ken Giusti
> Assignee: Ken Giusti
> Priority: Minor
>
> Probably not a realistic use-case but freeing the pn_tls_config_t instance
> after creating a pn_tls_t using it can crash:
>
> {{int main(int argc, char *argv[])}}
> {{{}}
> {{ pn_tls_config_t *tls_conf = pn_tls_config(PN_TLS_MODE_CLIENT);}}
> {{ pn_tls_t *tls_session = pn_tls(tls_conf);}}
> {{ pn_tls_config_free(tls_conf);}}
> {{ int rc = pn_tls_start(tls_session);}}
> {{ if (rc != 0) {}}
> {{ fprintf(stderr, "Failed to start TLS session (%d)\n", rc);}}
> {{ return 1;}}
> {{ }}}
> {{ return 0;}}
