Ken Giusti created PROTON-2851:
----------------------------------
Summary: 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
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;}}
{{}}}
